Q: I decided to try this formula for my baby since he started being very gassy. However, this formula made him more gassy...the formula is very thick and produces a lot of bubbles that gets fed to the baby. I tried to make the formula with anticipation to let the bubbles disolve but that didn't work.

A: Negative
