Am rather concerned having just read a Times info about puberty for overweight toddlers starting 'as early as 9' - was already concerned at having spotted a couple of pubic hairs on DD1 (8.5) recently (not deliberately I assure you!!) who is, if anything, too thin. No boob development though someone in her class (also v skinny) already has a bra. How soon does the other stuff start to follow? Is there anything I can/should do? It just seems rather young but she's never been overweight though is quite tall for her age. Can anyone tell me the 'normal' age please?
