I gave this product to my 2 month old to help with gas and it did more harm! Extremely gassy now, tummy pains and just overall discomfort . She cried while feeding and didn't feed again until six hours later. I don't know if her tummy just needs to get used to this product but I'm never giving this to her again!! The box says 0.5 once a day but on amazon it says 0.4, so which one is it? Just beware parents!! I went from just having a gassy baby but happy to a colicky baby that doesn't want to eat! I feel like a horrible parent now, my poor baby.
