Lavender DOES help us all sleep, and is used for relaxation in aromatherapy, but the lavender in the J&J is probably outweighed by all the other weird chemicals in there. See if the massage itself with olive oil or sweet almond is enough to help him dream and if it isn't you can get lavender essential oil relatively cheaply at wholefood shops (one bottle lasts AGES). If you want some baby massage techniques i could do a new thread? I have a couple of books on it.
