I used infants friend with both babies until about 3-4 months as the colic seemed to ease off then.

I couldn't live without it - it made such a difference and I was talking to someone at an ABA meeting who said her naturopath looked at it and said other than one ingredient that is what she would have made up for the lady's daughter.

I used it before feeds in the morning and at night and that was enough to do the trick and help with sleeping.
