My daughter is 9, she’s a younger 9. She still likes her Sylvanian Family and playing with her ponies and I love that. These last couple of months she’s developed hair under her arm pits and is regularly getting pimples. Her emotions have been a little more volatile. She asked me why this is happening the other day when she was looking at her spots..... how much is enough information? Do I explain all of it? Is she too young to know?
