Help! Baby is 11 weeks old and have been primarily breastfeeding with occasional formula top up. Almost 2 weeks ago suddenly started getting what looked like green diarreah after feeds. Have been to doctor twice and they say baby is fine. I cant wortk out whats wrong. It happens with breastmilk and with formula. It's not dairy issue as there's no hives etc. Ive made my diet stupidly healthy to avoid anything. At loss what to do...getting zero sleep. anyone got any ideas?
