Been prompted to post this thread because of the 'how often do you wash your child's hair' thread.... I never wash DD2's hair because I just can't work out how to plug her ears properly since she's had grommets in. Doc said to use cotton wool and vaseline, then presumably roll them into a ball and stuff into the ear, but they always fall out. Can anyone explain how to do it properly please? Or suggest alternatives? Thanks very much!
