My baby is 7 week, has had problems with tummy pain since birth. We’ve ended up on prescription milk Pepti 1. He is still in pain and straining straight after a feed and pretty much the majority of the time. His trumps also smell really really bad no exaggeration which surely they shouldn’t smell too bad for only drinking milk. I wouldn’t say he is constipated - has been going every other day. Has anybody got this or have any advise. I’m losing my wits
