I didn't think it would really...wasn't going to try it, however much I want to make his discomfort go!...Don't even take pain killers myself, totally anti drugs so wouldn't plaster my baby up with it easily...didn't know it was 2m+, havent had the need to use it....any other colic relief ideas ladies? tried infacol, dentinox and gripe water...not sure if it works, should it work right away?
