Reassurance needed - 3 month old sleep

[MyBalletShoes]

13 week old DS2 is just not sleeping at night.

He wasn't great before hand with his sleep, up every 90 minutes or so, but it's just atrocious at the moment. I'd take 90 minute blocks in a heartbeat now.

He had his 12 week imms on Tuesday, slept ok and from Wednesday afternoon onwards became quite grouchy. He just doesn't seem to know what to do with himself.

DH is on holiday at the moment so for the last 2 nights has stayed up with him downstairs all night, bringing him to me for feeds, and is catching up on sleep in the day. Obviously this can't continue when he gets back to work.

DS2 is up and fidgety every 20-30 minutes. We keep cuddling him and putting him back down whereupon he either cries straightaway or settles for 20 minutes then is up. This happens in both the Moses basket downstairs and his cot upstairs in our room. Co-sleeping has stopped working and even when we let him sleep on us he's just so restless. He's also quite fussy at the breast and while still taking milk he's really not bothered by it and it's giving him no comfort.

I know there's a 12 week growth spurt and there's the jabs the poor lad has had to contend with, plus someone told me a wonder week can happen around about 3 months?

Can anyone offer any reassurance as I'm just so incredibly worried this will never end. I can't see past this although DH is wonderfully reassuring that it's just a phase. But what if it's not?

Thanks in advance.

Also wanted to add he's perfectly happy in the day. Alert, smiling etc. Even sleeping ok with a few 30-40 minute cat naps during the day. It's just the night where it's all going to pot.

I don't really have any advice, just sympathy!! I have the wonder weeks app for my DS (10+5) and they apparently go through a leap between 11 and a half weeks and 12 and a half weeks (that's from due date), so if your DS was on time then you're bang on for some tricky behaviour! It's only a week though, so if it's just that then fx it should be over soon? The fact that he won't even sleep on you is unusual, how many nights has he been like this? It could be colic - have you tried Infacol or similar? Might be worth a chat with GP.

Thanks so much for replying Nessalina!

He was quite colicky or more windy really since birth but that seems to have eased off over the last week or so. Really hoping it's just a developmental phase that passes although I just can't see the light at the end of the tunnel at the moment. DS1 had terrible sleep regression around 4-5 months but would at least be put down.

I'm not really sure what the GP would do. Or HV for that matter but if it goes on for much longer it might be worth a try. A dummy might help but he just spits it out so that's no good. Am looking forward to when he can roll around and find a sleeping position that he likes but that seems a long way off.

Had definitely forgotten how hard these newborn sleep patterns are.

Yeah, just when you think you've found a pattern, it changes!! People say 'everything's a phase' with newborns, and it's totally true, but it's hard when you're going through a tricky one
