So my newborn is 3 weeks and was on enfamil newborn at first since she came home from the hospital, then we started her since couple of days on enfamil infant cus that's what the WIC gave us and the doctor before we left said it was okay to. but she's been so fussy and been drinking a lot like she's not getting full and after she spit up on and off. I feel like she has gas also, shes been popping and I feel like her tummy is hurting her I just don't know if the formula is not greeing with her cus it's only been almost a few days since she's been on it. I don't know if her body still getting use to it. HELP PLEASE 😓
