Really struggling with my 8 week baby, as soon as we introduced Formula she started with really bad trapped wind and green, mucus, 💩. The pain she gets with it is so bad, lasting hours. She was changed to Althea which didn't help and is now on nutragimen. Initially nutragimen helped and she was settled and 💩 started to look more "normal". However this only lasted afew days and now we are back to pain and nasty poo, yesterday she had a very small amount of yellow vomit. Is this CMPA or could it be something else? Professionals haven't been that helpful, waiting to see paediatric consultant. Any advice or guesses what's going on? TIA
