I have a 7 week old with CMPA and his poos and face rash looks like this. He also constantly has trapped wind, so bad it keeps him up most of the night. I’m currently 9 days dairy free (had 2 slips so far - completely accidental). Started our DF journey on 30th March. On day 6 of being dairy free his symptoms start to get better! The only way to find out if it’s CMPA is to eliminate dairy and monitor their symptoms, then reintroduce dairy after you have completely detoxed and see if they have a flare up again. My baby had a bad flare up both times I slipped up since being DF, so I’m 99% sure it’s CMPA!
It's possible, my first had this and these are how his started! Hopefully not though!
