Does anyone have any experience of constipation in a baby being down to cows milk allergy? This was suggested to us by one doctor as a possible cause of dd2's chronic problem so she's now on a completely disgusting prescription formula (in addition to breast milk) which she loathes. Everytthing I've read about cows milk allergy talks about diarrhoea and vomiting being the main symptoms with no mention of constipation so i'm wondering if this is a red herring, specially as she's shown no particular improvement from being off cows milk for 2 months. i'd love to put her back on her old formula (SMA gold) as at least she liked it but of course don't want to do so if it may make things any worse for her. any views?
