Gerber Probiotic drops

Tiffany

My 5 week old has crazy crazy fits and the doctor things it is colic or reflux. My daughter was put in pepcid for a few weeks to see if it works for her. But has anyone tried to Gerber Probiotic drops for gas and colic? If so, did it help? How long did it take to work if it did?

Any advice is appreciated!
