Colicky baby lactose intolerant

Korina

Any tips on colicky baby? My daughter was on similac advance till she got super fussy her doctor recommended similac sensitive due to her being lactose intolerant he also believes she has colic. she’s still so fussy it’s hard for her to burp even with gas drops we also give her gripe water it doesn’t seem to help her at all. I’m just at loss on what to do or what formula we should try now. Any advice?
