Regression help please ...

[NomsQualityStreets]

DS2 is just over 3mo and is going through a sleep regression.
He has gone from sleeping 8.30pm-1.15am and then waking 2 more times for a feed until about 7.30am ish to waking anything between every 15-45mins.

He's windy when he does and needs dummy and a little rock in the snuzpod to fall back asleep but wakes up again within 5mins sometimes
I am so tired and ill ATM my whole body aches and I just want a couple of hours of uninterrupted sleep.
How do I help him?

I've read somewhere that this is a good time to teach a bit of self soothing but I have no clue where to start.

TIA

Hopeful bump.

I feel like death warmed up and keep going dizzy when I walk around, I'm dreading tonight.

Hi OP, if he is waking up after 15 minutes, could he be hungry? Ff or bf? Either way may be worth upping milk intake. Try infacol / colief for wind although this will take a few days to kick in. Do you have a partner who could take over so you get some sleep in? How are naps in the day? Can you sleep then or is it more cat naps? I think self settling is quite tricky at this age. Of course, if baby is just fussing you can absolutely see if they settle down but I wouldn't leave him to cry at such a young age. You could try swaddling / white noise (incidentally I have found white noise needs to be quite loud to work - I play a track on spotify on maximum volume on my ipad). Good luck.

Thanks @KatnissK he sometimes wakes up and immediately cries loudly.

I don't think he's hungry as he is fine in the day, I'm EBF btw.
At night if he's been up multiple times within the hour I usually try to BF just in case he is hungry but he's often not interested. He gets unsettled and brings his hands to his face and kind of moves his head from side to side knocking his dummy out. I end up having to hold the dummy for him until he starts sucking it himself and then rock him.

He naps ok during the day. He's had a longer nap today in the afternoon, probably catching up from last night.

I can't really nap with him in the day as I also have a toddler to look after.

I would wake at every feeding as the regression coincides with a growth spurt and also feeding gets back to sleep quickly. It’s rough but it passes.

Sorry I meant feed at every waking! Ha.

I couldn’t disagree more that they’re crying just because they want to go to sleep. Babies need comfort to go to sleep, whether that is parental or a dummy or similar. It’s unkind to take it all away.

Thankyou for all the replies.
Last night was horrendous he was up at least 15 times and I was running a fever and soaked the mattress. I ended up putting him in bed with me and he finally had 2x1hour stretches.
I'd be crying right now if I wasn't so dehydrated.

Nothing wrong with cosleeping mama, especially at times like this. Any sleep, anyhow is my motto! It won’t be forever. I’m so sorry you’re ill, but even more reason to rest however you can. It won’t last I promise x

Thank you @crazycatlady5 I just feel a bit down about reverting to cosleeping as I only recently managed to get him to sleep in the snuzpod and not on me.
He's currently napping probably catching up on sleep after last night.
I keep breaking out in cold sweats and it's really not helping, it wouldn't be so bad if I wasn't ill.
