DS has stopped self soothing in the night

[StepsRoadmum]

We've been very lucky with DS and his sleeping at night and just after 3 months after a rough patch of sleeping he learned to suck his thumb and soothe himself to sleep. He had been sleeping 10-11 hours self soothing if he did stir. He is put down to sleep after a feed drowsy but awake and has managed to get himself settled. A few nights ago that all changed. He is still put down in the same way with the same routine at 7:00pm but is awake by 12-1am and again 4-5am and then wakes up at 7-8am. I know it's only a few times he wakes but he cannot seem to soothe himself and now the only way to get him back down is with a feed. It's just frustrating as he used to be able to self soothe. I'm fairly sure it's not the 4 month sleep regression as I'm pretty sure we went through that at 3 months, then he learnt to self soothe and it's not as bad as every few hours that he wakes. Anyone got any ideas at what might be going on?

Self soothe? Sleeping through . I'M sure I told my toddler they were on his to do list!!
Clearly I have no actual help as I'm awake because my can't do it at 28 months!!!
Just though I'd save you feeling alone 💐💐

I haven't followed wonder weeks completely but have heard references and have always assumed that this is what is going on.

This will happen with new learnings and skills. After these changes he may have forgotten how to self soothe or find a new way or go back to the usual way.

But I'm afraid there is no "cure" for this. Just roll with it and remember they are going through massive changes.
Might also be a growth spurt and he needs extra feeding?

I've found that you can't even be sure what is exactly going on until after the phase has passed! And they do pass eventually.

Have you tired co-sleeping? (If not already). Might be easier to settle down again or at least easier for you without having to get up!

Hope you get some rest.

Do you feed him when he wakes? It’s still quite young so I imagine he’s either going through a growth sprint and needs feeding or it is the sleep regression.

@SleepingStandingUp thanks for the response, I feel bad complaining now. We did have it really lucky with him.

@DasPepe we have the Wonder weeks app and do keep an eye on it, it seems fairly accurate with our DS normally and it says he should be coming to the end of a leap so should be over the worse of the fussiness but it could still be that.

I'm starting to think a growth spurt is the most likely answer so just going to go with it and continue the night feeds and see what happens.
