Advice on two week old baby please!

[KMG30]

Hey!
Please can I have any advice, I’m a first time mum 🙏🏼
I birthed my twins at 37 weeks on 30th January. They are amazing and I’m soo in love!
My boy has no issues so far
My girl was a bit more weak when born and had an over night stay in neonatal due to breathing but all okay now. Since coming home two weeks ago she has started straining. She strains very often, no pattern - can be after feeds or in her sleep, she goes red in the face, makes a straining noise, while arching back/scrunching her body/moving legs etc. she doesn’t cry though! This will last few seconds then she stops.
She is not constipated
She does not vomit after feeding
She feeds well. Currently 8 bottles a day. 4 breast milk during the day & 4 formula during the evening/night (Aptimel)
She doesn’t wind well, I barely hear her burp, she farts more often then burping
Currently drinking 2.5oz to 3oz, sometimes she could drink more but I don’t want to over feed her!
Midwives very happy with her weight
Introduced infacol on Friday to help with burping. It has made her fart loads & burp a bit better.
BUT Friday night & last night she did not settle well at night at all. Last night she was up mostly all night. After a feed she’ll go down for about an hour then wake up screaming. I tried to settle her as long as I could before feeding her again so we made the 2/3hour feeding time. She then fed well but still didn’t settle. Would you up her feeds? She seemed hungry when crying during the night. But also a consultant said she is already eating too much!

During the day she has been totally fine and sleeps during the day
My theory could be maybe it is the formula? As she has the formula during the night. Ah I don’t know!!!
Any opinions please?
I don’t want to over use infacol for no reason if it is not needed - but it did make her burp more. Could it cause more pain for her?
She also has very mottled skin. Some days can look quite bad, I took her to see a peaditrician but they was not too concerned about her skin and just told me to keep an eye.
sorry for the long post and thank you for reading!

If you think it’s wind you could try gripe water. I think there’s another called colief or something similar.
Some babies do have CMPA and for some the signs are a rash and being uncomfortable after feeding.
Hopefully someone else will be along with some other suggestions.

We had a newborn that required formula top up and we noticed she was crying more especially in the evenings and we changed the formula recently to goats milk one and she's a new baby! Barely any screams. Same brand just not cows milk so I'm assuming its that. I don't want to give one that doesn't have any lactose in it but lowering it has helped. We use colief/lactose binder also. Sleeps great now. The odd trapped wind scream but it's nothing in comparison. Infacol didn't work for us. Try baby massage too and sorry to say it - dummy! Dummy and white noise really helped lo calm more after a feed. Just make sure you know her cues of when she is hungry and when she just wants to self soothe. Good luck!

Sounds just like my CMPA baby. You could try cutting dairy and probably soya too out of your diet and discussing with your GP getting a prescription milk xx

Thank you. I was looking to switch formula and see. Would you switch it for both babies or keep my other twin on the same one? It’s going to get confusing two different formulas haha!

Thank you. I will get GP appointment this week! X

If there's no issue with the twin then I maybe wouldn't switch formula as it could upset tummy. What I did was actually start with 2 normal formula and 2 new and then up it to 1 and 3. Mainly so it uses up the old formula too and even that helped. We used kendamil but I've seen and heard nannycare are meant to be good. Everyone says they are all the same but I thought if I change from cows milk to goats milk with the same brand then likely the same ingredients for most of it hence the mixing to ease her into it. Please let us know how things go. I know Dr's tend to give gaviscon but we've not needed to use anything yet so I would try that first.
