Yes it does. You could try aptamil which is closest to BM and helps maintain gut health

Hi, it depends on which formula milk you're using.. I use Danone's Aptamil with prebiotics so she never faced any colic infact it helped her with constipation and colic both.. it helps in easy digestion too.. this was recommended by a dear cousin and well tried too.

Yes it can cause.... How old is the baby??? It's always recommend to go for exclusive breastfeeding
