Sudden issues with feeding - help!

[dcoco25]

Our LO is 12 weeks old today. Shes on a hypoallergenic formula for suspected CMPA. For the past few weeks, shes been feeding really well, gas has been getting loads better etc.

This week is like a different baby! She fights every feed, will barely eat 100ml each feed and is kicking and squirming after for ages. We're burbing her well throughout. Im not convinced its reflux but im worried with how little shes now eating in a day. Any ideas?! Its making feeding exhausting 😩

She was on Dr Brown bottles, have tried MAM but hasn't really made a difference.

Which milk is she on @dcoco25? If she’s one of the hydrolysed formulas that still contain dairy she may need to be switched over to a completely dairy free formula. It’s common for babies to improve for a while on a hydrolysed formula and then for symptoms to return unfortunately.

@BunnyRuddington she's on nutramigen which I know does still contain some milk protein. Shes been slightly better today with the fussing but is still eating much less compared to what she was.

Weve been on the formula for about 8 weeks now and no other side effects showing! Strange one.

If the fussing is better but she’s still drinking less, how much is she taking? She should be having roughly 150 ml of formula a day for each kilo she weighs. Is she having a lot less than that?
