I never used it. Too slimy. I used lavender baby lotion. :>)
I sometimes put a little on my baby after a bath. I put her on her tummy and rub it into her back and legs. I just hate how greasy it is.
You used it to give your baby a light massage after bath etc as when you touch them they become more aware of themselves and there body's. Etc fingers and toes. And it can be a bonding thing. It's not Nessacry though.
