Neosure switch

My 34w6d baby who is 1 month & 2 weeks actual and 1 week adjusted is going through it with neosure. Gas, colic, fussiness, reflux.. I mean she’s literally NEVER happy even when she’s fed, burped, changed, well rested.. she is already on probiotics and the ped okayed for us to switch formulas. We tried gentlease and it caused for her to have awful diarrhea & no change in behavior so we went back to neosure. All that to ask, what did you switch your babies to? Is it just a phase? Any insight on byheart, bobbie, kendamil organic?
