My DD will be going away with the school in 3 weeks time for 3 days. She will be 10 and a half. She has not started puberty yet, as in she doesn't have breast buds. She gets greasy hair and is moody sometimes so no doubt things are cranking up. Do you think I need to get some sanitary pads for her suitcase just in case? Can periods start ahead of breast buds? I am thinking impossible but maybe I'm wrong!
