Any mommas ever tried enfamil gentle ease and similac sensitive? And how did It work out for you? My daughter is very constipated gassy and fussy and I'm pretty sure it's her formula. My doctor told me I can switch to see if it gives her any relief but I'm not sure which one. I'm also lactose intolerant so I think she might have got that from me. TIA.
