B.O in a 7yr old.

[muggglewump]

My DD, 7.1 has been getting B.O. I first noticed a couple of weeks ago but if she runs around and gets sweaty it happens every time. Of course I bath her every night now but could this be a sign of early development, and if so is that a medical problem in a girl so young?
She's seemed to be putting on weight a wee bit, although I only really checked when I noticed the B.O and she's in no way fat. (I haven't weighed her, just noticed when she's naked) Still fits clothes for her age, in fact the coat I bought her this week, age 7-8 is too big.
I developed early, started my periods at 10.9 and was the tallest girl in primary school. Funny really as I'm 5'2 with 34B boobs, but 7.1 seems very early
I'm a bit worried, does anyone else have any advice/experience?

If its any help I noticed the same about my DS when he was about 7.5. If you search on here there are some helpful threads which I looked at. I got him a natural roll on deodorant (Holland & barrett I think) which was expensive but apparently normal deodorants contain something (aluminium?) which can be harmful to small children.

My Dd was 7 this week and I noticed her smelling a bit sweaty a few weeks ago. I was trying to get her earring back in and she was getting worked up and sweaty. I couldn't believe she had body odour! My other DD is 10 and has only started to use deodorant.

Thank you, I'm so relieved.
I will get her some of the natural deodorant.
I was worried she'd start her periods next week or something!
I'm not one to keep her a baby or anything but the thought of puberty when she's very much 7 is scary.

AFAIK development tends to be genetic though? Does that mean DD is likely to be early, and as it has been getting earlier over generations would it figure that DD would be earlier than me?
