I am a FTM and I was originally supplementing LO with Similac Advance and she was at the time getting more breast milk to formula ratio. Now that she's requiring more I'm making less breast milk and she's getting more formula. Due to some gas issues we tried her on the Similac Sensitive and noticed more bubbles and foam to cause her more spit up and to choke frequently (I think it was related to moisture getting in the formula container) so we put her back on the Similac Advance. Now with 75% of her intake being formula I notice her to be so much more gassy plus she's constipated where she's waking up crying and grunting and straining. Her Pedi recommended gas drops which she's been on for 24 hours now with not much improvement. My question is has anyone had any of these problems with their LO being on a certain formula and what did you do? I feel awful for my poor girl and I hate to think she's in pain

I've heard good things about Enfamil Gentlease but I hate to keep switching formulas. Any help/recommendations would be much appreciated!!!
