Quoting Momyof2Girls:" she finally settled down but she has belly aches alot. could it be the formula?"
absolutely. my son was having a hard time with his formula that we had him on (he was getting similac) and he would scream and scream for hours and NOTHING would make him stop - he wouldnt eat or sleep or anything and no matter what we did he was miserable. i hated it.
we switched him to enfamil a+ gentlease which is specifically for gassy/fussy babies and hes doing wayyy better with that one. hasnt had any tummy troubles at all on it. plus, its cheaper ;)
