From 12-18 month J slept through the night and we had absolutely no complaints about his sleep. When the 18-month mark hit, we experienced a very sudden and challenging regression with his sleep. He had consistently been going to bed around 8pm and waking around 8am, but all of a sudden he protested bedtime, and had wake-ups every two hours until morning. During those wake-ups there was a lot of inconsolable crying.
We sleep trained back when he was 6 months old and it had worked well for us, but at 18 months his cognitive and perceptive skills were impeccable. Sleep training was an entirely different scenario when our child knew we were right outside and could hear him. Another thing that had worked in my favor during his first 16 months was that he was breastfed, and it felt like the magic card up my sleeve. If all else failed, I always knew that would comfort him. But when he self-weaned at 16-months, that was no longer in my box of tricks. Additionally, he had recently weaned off the pacifier prior to 18 months. Mr. Pen and I were out of cards to play.
While getting through the 6-week long sleep regression, we had a few nights of trial and error. Here are the things that worked for us:
Modifying bedtime routine
This was the biggest change that ultimately improved our process and how J slept. Prior to 18 months we had a simple routine of bath time, pajamas, one book, one song and bedtime, all in all taking less than 20 minutes. But at 18 months he appeared to be having a harder time with the transition, so we decided to rearrange things and add in extra time for him to make the transition more seamlessly. Instead of one book, we would read three or four. At this age, he started to enjoy being the facilitator of which books would be read before bed. We also started allowing him to have some quiet one-on-one play with us in his room that involved things like puzzles, imaginative play, coloring, blocks and occasionally a ball game. He also started asking for more than one song that we would sing while holding him and swaying back and forth. We love this lullaby, and he started singing along as well. As he became more musically inclined, he started requesting songs he likes such as “Twinkle, Twinkle Little Star” and the “Tiger Song” (from Daniel Tiger’s Neighborhood).
Extra Time
I mentioned this a bit in the previous section, but allowing him a little extra time to make the transition helped us a lot. We ate, and now we still do, eat dinner between 6 and 6:30 p and have bath by 7pm, which allowed for nearly 45 minutes for the entire bedtime routine. The transition had finally become much more seamless when he had time to anticipate that it will be bedtime, and knowing exactly what his routine was. In fact, if any part of the routine changes even now, he is the first to notice and ask for that particular thing (such as if we skip bath time).
Middle of the night wakeups
The hardest part of the sleep regression though was going back to middle of the night wakings. We started rocking him again in the middle of the night, and usually singing a song. But there was a lot of crying involved, and I’m not sure if he went through a spell of having bad dreams? But many things were no longer soothing to him. There were many nights where he simply wasn’t tired anymore at 1am, and wanted to run around and play. On those nights, it was useless to try and hold him in our arms to rock him, or even put him back in his crib, as he would just wail. So we would let him walk around and pull out toys, however, we always kept it dark. Where we live there is a decent amount of streetlights coming through our windows, so he always had enough light to see to walk around, but we never wanted to encourage his wakefulness by brightening the room. This seemed to help keep those midnight play sessions short. Allowing him to play, even just for 10 minutes, usually helped him release what energy he had, and go back to sleep. But we didn’t make a habit of this, and still needed a wind-down time such as rocking and singing songs.
One thing that didn’t work anymore was taking him into our bed, which I had done a few times out of pure exhaustion and desperation. But instead of it being consoling and a special treat for him, it meant playtime. Needless to say, it didn’t take more than two or three times to learn that co-bedding would not work with our toddler!
After a very long 6-week period, his sleep finally returned to normal and just a couple months later we also transitioned to a one-nap schedule. He is 24 months now, and back on his 8pm-8am sleep schedule.
Did you experience an 18-month sleep regression? How did you handle it?

GAH! I didn’t know this was a thing! Just when things were finally looking up….maybe we shouldn’t paci wean just yet…

@Mrs. Lion: honestly, J has been going on and off the pacifier for over 6 months now! He was weaned, then found an old one months later and wanted it all the time. At two he asks for it at bedtime, but never during the day. It’s tough, cause I’m not sure what to do. At two years old CIO doesn’t work so I’m not sure what else to do!

We didn’t experience any sleep regression at 18m, but the 4m one was enough for all the regressions put together! I still shudder at the memory.

We didn’t have the 18-month but now at 23 months I think we are going through the 2-year sleep regression. I am so tired because she was up from about 2:30 to 5 a.m.

Hum so this is what is going on. DD turned 18 months and sleep is the pits. She fights to go down, wakes frequently at night and if she can’t calm herself and we go in?…. All bets are off and the night is down the tubes
our 4 month sleep regression lasted two and a half months (!!!) so I pray this passes quickly. Thank you for the tips

We are just on the other side, although bed times are still a bit late (9pm instead of 8:30). Bringing her to our bed did work for a while, but the first two weeks of wake-ups and crying were do hard. She resisted and sometimes skipped naps too, and even though we still bf, it want much of a comfort.
Once I recognized it would be six weeks, we just made due, and sure enough, it was over as suddenly as it started.

We too experienced an 18-month regression. It was so surprising as he had been sleeping through the night since 9-months old. The first two nights I tried consoling and co-sleeping to no avail. The third night we did cry it out for both bedtime and the middle of the middle wake up. It sucked, but worked. Our daughter will be 18 months next week. Crossing our fingers that she passes right through that phase without the same trouble as her brother.

Wow Im glad we never went through this. Ds didnt sleep through the night till one year though so i couldn’t imagine what Id do if he regressed so shortly after!

We just went through the 12 month regression. THE WORST. Luckily no middle of the night wakeups, just very early – like up for the day at 4:30am. We made it through and now we’re back to 12 hours at night.

Both of our kids have had really rough sleep regressions at around that age. Our eldest started at around 16 months and although the night waking passet fairly quickly, we found ourselves in a new habit of sitting with him until he fell asleep (sometimes for an hour) until he was 20 months old. With our second child, I think/hope we are at the tail end of it now. His started before 17 months and it’s been almost 2 months now. The night wakings are getting fewer and he seems to be going back to falling asleep quickly on his own, but we could do without the 5:30 wake-up call! It’s so weird how they get into a regression from out of nowhere, literally overnight. And after the first child, you know to just brace yourself and get through it since it often disappears just as suddenly as it appeared.

Ugh. We are in the middle of this right now. I’m waiting until it’s over to blog about it… We’re almost starting week 3 of it so fingers crossed we’re nearing the end.

Little P has had night wakings on and off ever since he started teething.
I can’t remember if the last one was right at 18 months or not. We’re just REALLY big fans of the Early Bed Time, and when he starts having night wakings we start putting him to bed earlier and earlier (often at 6pm) for a few night and he usually recovers from his sleep debt and will start STTN again.

Oh, gosh, this post and the comments are killing me! The boys are finally sleeping through the night, and I hadn’t really considered sleep regressions from here on out. I’m glad to hear it’s over now, and I appreciate you sharing what worked and didn’t worked. Fingers crossed that my boys will just be the most amazing sleepers ever and never have another sleep regression. A girl can dream, right?!?

we are currently going through this regression I think. My daughter is 19 months old and all of a sudden fights sleep…won’t even say “night night” anymore she has such an aversion. The whole house is operating on practically no sleep. So this just goes away? I have had her ears checked just in case and nothing. Not sure how to handle it as she always self soothed if she woke up in the morning early or at night. We originally did CIO when she was younger, but seems she just gets angry now and cries out our names which kills us. Any suggestions?

we are going through this now at 22 months. She’s been sick, but had been sleeping fine (with an occasional cough waking her up), but the past week or so, it’s been inconsolable crying in the MOTN and wanting to go downstairs, not wanting to be held in her room. Hoping we come out of this soon! CIO didn’t work last night – and we were up from midnight to 3am.
guest
Wow it feels good to read and learn that we are not the only ones, my son is 18 months and this is new for us, the tantrums are crazy
we are exhausted. I try to hold him when he wakes but sometimes he doesn’t want to so ijust

I think we have officially hit the sleep regression at 16 months. Between my LO getting molars and no sleep I am like a mombie (zombie mom). We have been waking up in the middle of the night every once in a while…when he was sick or teething, but this is insane!! Last night he went to bed at 7:30p, was up from 9:30p-1:30a, woke back up at 3:40a-4:30a, and again at 5:20a. He was up for the day at 6:30a…and I work full time on top of t. Just shoot me! This has only been going on for about 3 days and I am officially dreading night time for what I’m sure will be the next couple of weeks. He was doing so good sleeping from 7:30-7:45 to around 6:30-7a, again with the occasional MOTN wakings. I am seriously considering taking a day off just to catch up on sleep while the boys are at school/daycare. I don’t remember it being this hard with my first son. Maybe I’m just getting older and tired faster! haha

I think this is where we are, but who knows. Night wakings started around 16 months-with 4 new molars coming in. Then we hit wonder week leap 10-which led to continued night wakings, early mornings and lots of tantrums. We finished the wonder week and had one blissful week of sleep again-all of us! Now all of a sudden at 17 months, 3 weeks we have had 4 nights of garbage-2 nights of 4am wakings, and last night took 1.5 hours to fall asleep only to wake up from 1030-2 and up at 520. We have done CIO in the past, but it is so much worse this time-he screams forever. I have no idea what to do and am losing my mind.

My little guy is 18months in two weeks and we have hit that 18 month regression. I just found out about this yesterday. I didn’t even know this was a thing. My son slept through the night since he was 9 weeks old. We were blessed with a great sleeper/napper. We had a couple hiccups here and there with sickness, teething, and what I’m assuming was other regressions. This one is killing my husband and I. He wants to do the CIO method but my son will not CIO. He will continuously cry until the end of time. My husband could also sleep through a plane crashing into our house so he can actually sleep through it. We’ve tried it all. My son will fall back asleep as long as one of us is lying in bed next to him. We have a guest room so we take turns laying next to him. He’ll fall back asleep in 20 mins and we could take him back to the crib, but we usually pass right back out next to him. I don’t want to develop a habit but he’ll go to sleep in his crib, just not after he’s woken up and screaming in the middle of the night. It’s tough. My daycare lady gave me some comfort in saying that some kids will never ever change regardless of what method you use. Every child is different. Hopefully this is just a regression and a short one.
guest
Omg! I didn’t know about this and feel relieved as my son has been doing this for the last few weeks and thought he was just teething but I’m exhausted as he is running around my lounge at 10pm at night after crying in his room for over an hour to get up! Waking up at night crying and wide awake. Feel like crap and look worse!! How long does it last?

guest
Well so pleased I found these tips to try!! My 15 month old has just started this! My husband works evening I work nights and I’m pregnant and I’m currently doing 2 hours sleep a night due to all the screaming and waking! Hope it doesn’t last much longer and we are only on our second week!! Going to try all these tips- having dd in our bed doesn’t work for us either. It’s so reassuring to know this is a thing and it’s not just me being a useless mum!! Thanks guys
good luck everyone X x

So that’s what’s going on!!! I never experienced this with my daughter. This is new to me. We are 4 weeks in…. 2 more weeks to go.
guest
Hi, we are facing the same problem, but mainly for nap time. He is already on one nap routine fro sometime. And it’s about 2 weeks that he has started resisting it! He is (was) trained to sleep on his own. Now on and off he refuses and cries a lot!!!! Waiting anxiously for this period to finish!! Have to mention that I can see how his brain has become active. He memorized the whole picture book of transport in 3 days!!!!
guest
Omg I’m at my Whitts end my 17 almost 18 month old is awful. She is great during the day has a long 2 hour nap. We still have out bedtime routine but I let her stay up a little later as she fights bedtime. I am dealing with her every night myself as my husband works. She will sleep in her crib for the first 3 hours then wakes up, stands up and wants to come to bed with me. She is fussy, moans, groans, cries and we’ll I get no sleep. I tried to put her back in her crib and she just freaks out and screams….idk what to do I’m trying to hang in and stay positive but it’s killing me I need this to be over

I have been reading all of you stories and relate to most . My daughter is going on week four of this 18 month sleep regression. She has slept through the. Ugh since she was around 8 mi the old. She was also diagnosed with strep throat right on the middle of it which I thought was the culprit but after 5 days of antibiotics she is still waking 3 times a night . I have to rock her to sleep or she will cry until she vomits or sounds like she is hyper ventilating. So does this go away on its own or what ??? I’m losing hope that she will ever sleep throughout the night again !!!!!!
guest
Can anyone share how long this last or have any other tips to help us moms through this ??? I see that most posts are several years old …. any out there still dealing with this ? Help
guest
