My lo had lots of problems with this and it turned out to be lactose intolerance. Also ive heard Hipp organic formula is supposed to be helpful with this
Check for a formula issue
With my daughter when she was a baby I was told to use dark kayro syrup. It worked great. I put very little in her bottle (like less than a spoon full) and it helped her go. Even the doctor said it was ok.
Use Gripe Water. It's all natural and works wonders...used it with both of my first two and will this time if need be.
