How early can the four month sleep regression happen?

Hello - FTM with a possibly very stupid question. Can the four month sleep regression happen when the baby is actually only 3 months old, and before the baby starts trying to roll and roll at night, or are they always linked?

Our DS is just over 17 weeks now and has been a terrible sleeper since birth. He never slept more than a couple of hours, usually on us and it was always very difficult to get him to go to sleep - he always needed lots of help, even for naps and even when he was tiny, being rocked, swaddled etc, for hours and a few weeks ago he got even worse: he would sleep for 25 mins at night then cry for 45 mins all through the night which nearly killed us, and even in the sling it would take him nearly an hour to drop off, despite being clearly exhausted and ‘ready’ for sleep according to his wake windows. In the last week though he has transformed; he’s sleeping longer at night and he’s often managing to self settle as part of that if he wakes up. We’ve taken him out of his swaddle and he now usually puts himself to sleep chewing his hands, and is finally going down for naps without a fight.

As these last months have been so tough I have been really worrying about how on earth we’ll cope with the four month regression - but is there any chance that we’ve had it early and not realised because his sleep was so bad there wasn’t anything much to regress from?! I always thought it only happened when they started to roll, and he actually rolled for the first time when he was less than 3 months old and can hold himself up really well now, although he hasn’t tried rolling at night.

My DS’s started at 16 weeks and stopped at 24 and my DD started early at 13 weeks but was over by 18 weeks so yes I think it can start early! It was really clear when it hit, naps only 45 min to the minute and waking every 45 mins at night. Hope it passes for you soon. I have never been so exhausted, it’s a killer!

Absolutely can start early, it's really badly named tbh.

In our case he started sleeping badly from 2 weeks and didn’t stop until we finally did sleep training at 6 months. So there was either no regression or it was one giant regression depending on how you look at it.

My daughter hit the sleep regression at 3 1/2 months. She had been sleeping an 8 hour stretch up until that point.

Thanks so much for your replies. I guess what’s puzzling me is how we would know if it’s hit us if our baby never slept well before - I can totally see if a baby goes from 6 or 8 stretches to then waking every hour it would be so clear, but if they’ve only ever slept for a few hours at a time and always fought sleep would we notice a big shift in their sleep? Basically I’m scared that now our DS has finally started sleeping for 5 hr stretches at 17 weeks it’s all going to go downhill again! I’m desperately hoping we actually went through the regression early when it was particularly awful a few weeks ago, without realising and now he’s out the other side. Which may be a touch optimistic on my part…

Sleep progression in the baby months and toddler years is not linear. It doesn't get good and then stay good.

Sleep progression is naturally a series of regressions and progressions. Not just at 4 months, but throughout the first 3 years.

So I'm not really sure what you're worrying about? Sleep wasn't good before, do you tried lots if things to help. Sleep is great now - fantastic, make the most if it. Sleep will go not-so-good again in the future at some point and like before, you'll try lots of things to help. And eventually it will improve again. And so it continues.
