Dd will be 16 in January and has very minimal signs of puberty (doesn't need a bra, very tiny smattering of hair, no periods) her twin brother is developing normally (broken voice, just about needing to shave etc)
She's not underweight, in fact despite being active she's a bit podgy, especially her tummy - she was skinny and tiny till about 12 or so when she grew a bit and expanded outwards. She dances between two and 5 times a week, dependent on how rehearsals are - that would be rehearsals where she is playing an orphan in Annie - the other girls are all year 6/7 and many of them are more developed than her.
I've tried researching and the only things I can find about delay in girls refer to being very underweight which doesn't apply, or things like Turner syndrome, which at 5"4' or so she's too tall for!
Should we be seeing the GP now, accept theres probably something wrong? She is very behind academically, her latest report has her varying between 1s and 4s currently in all subjects and she can't spell to save her life, so she really struggles at school despite trying so hard. I just don't want her to have something else to deal with...
