I was 11.5 when started. She is 10.2 has breast buds and starting to develop hips. Some yellowish discharge in pants. Had a bit growth spurt this year but nowhere near adult height yet and same height as her peers.
She has no hair under her arms or down below and no body odour.
I've given her some sanpro in her school bag just in case.
Does hair come before menstruation? I can't remember. Thanks!
