4 week old- no sleep at night

[Nicellen]

Have a lovely 4 week old baby boy. Born at 36+6. Been Home 3 weeks now, until Xmas eve would wake 2-4 hours overnight- formula feeding. Since Xmas eve does not settle from 11 pm till next morning around 7ish. Very noisy and grunts, pulling up if feet and legs. Only has a poo every 2-3 days but midwife not concerned. Started on Infacol in case of gripe/trapped wind. Had attempted gripe water but unable to get him to take the volume. Sleeps perfect during the day. At my wits end. Partner back to work tomorrow so I'm panicking and anxiety kicking in. HELP

It does sound like trapped wind, use dentinox colic drops, can be used from birth and you put it in the bottle, it's helped my DD no end, she used to get so grumpy In the evenings with trapped wind (now she's just grumpy coz she's overtired)

I had this issue, some babies basically "learn to poo" again hence the grunting. It did pass in a few weeks - I think we were passed it by 6/7 weeks but it was a killer. Do you have space to take sleep shifts? We utilised our spare room a lot!

Between 11-7 does he appear to be asleep eg lying down, eyes closed, but grunting and fidgeting noisily as if he couldn't possibly be actually asleep?

There's periods between 11-7 when he does look 'asleep' but for the pain part his eyes are open the last few nights. He doesn't cry Just is noisy. With him being prem I'm unsure wether to use his adjusted age to nap his sleep development or his actual age.

It could be grunting baby syndrome, have you looked this up? Totally benign and normal so don't let the word syndrome alarm you.

My dd had this...it drove.me.crazy!
