My 16 month old girl went through colic for 6 months ... after many formula changes, diet changes, doctor visits, etc.. I bought Equate Infant gas drops from Walmart(this is their brand)..my little girl was happy and pleasant to be around after we started giving her this. You can give them 1-12 drops a day..usually it works best if you give it to them before feedings and after feedings..as well as bedtime. It is safe and effective. I still use them on occasion when I know her tummy hurts or she is gasey. Hope this helps! They are only about 3-4 dollars a bottle and one bottle usually will last a month!
