15 month sleep regression

Hello,

Apologies in advance for the long post.

I'm looking for some advice, I have a 15 month old baby who we started sleep training a few months ago and only recently for the past month has he become really good.

For the past couple of weeks he had improved to the point that we put him in the cot after his bed time routine and he would grab his comforter and go to sleep without any crying and then proceed to sleep through the night for 10ish hours or on the rare occasions he would wake up, go back to sleep himself.

For the past three days however, he has been throwing a tantrum when we even try to put him in a cot (and also refuses to switch the light off himself which he used to like doing). We tried leaving him in his cot the first night he did this but he cried for an hour straight.

This has happened suddenly one day without any change to his routine. So he now goes to sleep on our shoulder and has even started waking up in the middle of the night and calls out for us and won't go back to sleep unless we pick him up. He also now takes about an hour to go to sleep, even with us rocking him.

I know there is sleep regression for some babies at 15 months as they become more clingy but I am just scared we will loose all the good habits we formed. Sleep training the first time around was painful and I don't want him to loose his ability to sleep by himself.

Has anyone else experienced this.

I'm just hoping to hear experiences of other parents on whether this is:

  1. just a phase and he will go back to sleeping in his cot?
  2. potentially if we need to reduce his daytime naps
  3. potentially we need to push his bed time back by about 30 -45 mins?
  4. worst case scenario - start sleep training again.

TL;DR
15 month old baby suddenly refuses to go in cot and takes an hour of rocking to sleep. should we be adjusting his nap / bedtimes?

Thank you all

Bumping this thread up after searching ‘15 month regression’ myself!

I’m in exactly the same boat with 15mo DS, who recently is waking in the night loads and refuses to sleep unless it’s on me or DH, and just like you it can take hours in the night.
I have to admit our baseline was never as good as yours, in that we did used to cuddle him to sleep and then move him into the cot, but at least he slept through the night, where’s we’re barely sleeping these days!

How is your baby’s sleep now? Is there light at the end of the tunnel?!

Adding to this in the hope someone can give me light at the end of the tunnel!?

Hi @LondonLady178 I’m two months on from that last post and we’re back to good sleep (in fact the best sleep to date).
I can’t quite pinpoint when it changed but for at least the last month DS has been sleeping all the way through aside from when he’s been poorly.
Just in time for the 18 month regression I suppose 😅
I hope that gives you some hope that this is just a passing phase. We didn’t do anything differently it just passed…

I’m in the same desperate boat right now so your message gives me hope @CityKity !

We’ve had a similar approach to sleep and I generally have to breastfeed DD to sleep then transfer her to the cot. Can I ask how yours adapted to sleeping at nursery/childcare? We’re starting next week in the toddler room and I’m absolutely dreading how she’ll manage to get any sleep there!

@WherestheOffButton I’m glad my post gave you some hope. Fingers crossed your little ones sleep will get back on track soon.

I can’t help with the childcare issue unfortunately. It’s been a huge struggle for us too. DS was refusing to nap with his last childminder and would only sleep in her car. In the end we took him home for naps which was a pain. We’ve started with a new childminder this week, who’s happy to nap him in the buggy (which is how he normally naps). Yesterday he was with me all day and didn’t nap at all!

I don’t want to scare you though, as in general I’ve heard that kids behave differently in different settings!
