My son will be two months old tomorrow. My question is about formulas. Since leaving the hospita, ge has been on five different formulas : Enfamil Newborn ( caused gas), Enfamil Gentlease (caused gas and horrible constipation), Enfamil Reguline (horrible gas), Enfamil Prosobee ( relieves most of the gas to where he is not screaming to fart but he poops everyday however the poops are rock hard and green, screams to poop), Gerber Good Start Soy (doesn't help ease with any symptoms). I have tried 1 oz prune juice with 1oz water but causes him to cramp and scream in pain. Pear juice and water don't help at all. What should I do and which formula to use? By the way Enfamil Prosobee is not covered by WIC.
