My friends little girl had the refux problem, hers was treated with medication. Then when my friend had her little guy they thought it was happening all over again, but he ended up being lactose intolerant, they switched him to a soy based formula and he was fine after that. I thought my DD had colic too but my pediatrician told me colic doesn't last past 3 months, and she was over 4 months when I brought her in for that, he said she was just a fussy baby and would outgrow it, which she did, but she didn't puke much so I think there's a bit of a difference there. I would ask to see a specialist. Goodluck.
