So my daughter had been really constipated and the hospital started her off with the blue similac and she was fine then when we brought her home wicc gave me enfamil to give her and thats what constipated her really badly . Just 3 days ago we switched her to similac sensitive powder form and it got her WAY less constipated and WAAAAAY less fussy and gassy . I was concerned about the S.S forst ingrediant being corn sryup and read that liquid formulas are easier on babies stomachs so we then bought the similac sensitive ready to goes and my once waking up every hour , fussy , gassy constipated baby is now sleeping through the night . Which form of formulas do you mothers prefer 🙂?
