I gave gripe water (腸痛水) twice to my 2 month old baby. It doesn't seem very effective, i.e. my baby still cries. So I stop giving her la. Also later on I learnt that one brand contains 鎮靜劑. (I don't know which one) Then I don't give anymore la.
If you are worried about the content, then stop 陪月 ah!!
