My daughter was like this and she has CMPA. Does he cry a lot or moan a lot?
Also green is usually when baby has caught some cold or something like that
My baby has cmpa and his symptoms were exactly what you've described just with added skin rashes. His poos are also that colour and consistency even now with his new formula (sma althera) which is working wonders for him, he's a totally different happy baby x
My son was always hungry again after a feed so I used extra hungry sma formula and he would sick up every bottle and poo runny poo every feed until I switched his formula to cow and gate 1, doctors gave the infant gaviscon but never used. He is now very happy. He’s 13 weeks and now on 6oz.
Could be an allergy? Is it frothy?
