DD1 is 10, 11 in May. Went from very slight bumps to what can only really be described as pointy areola a couple of months ago. Looking at her tonight, she is in very definite rounded boob shaped territory.
When are they meant to start wearing bras? Is there a "when under breasts measures x less than around breasts" type deal?
She is very "young" in many ways, I have her in crop tops atm, and I can't see her expressing any desire to go into bras until she is nudged into it. It wouldn't occur to her if she is in secondary school surrounded by bras whilst she is still in crop tops iyswim, so going with "when she's ready" probably isn't the best option.
I don't want her in them earlier than she needs to be as I know she'll have a long time ahead of her in the things, but at the same time I don't want her lacking support if she needs it, just because I don't want to admit that my baby is rapidly growing up.
I bought my DD1 bralets from Marks before Xmas, got a couple of different sizes i.e. 28AA and 30AA, let her try them on and she has been fine with them. I talked to her about the skin above the boobs getting stretched unless she was properly supported. She was 10 and turned 11 this month,
measure under the breasts and measure around the fullest part. The under bust measurement is the bra back size. the difference between the 2 figures is the cup size. I don't know if anyone is ever a AA cup size as that means both measurements are the same.
each inch difference between the figures gives cup size e.g AA - figures are the same, A - 1 inch different, B- 2 inch diff, C-3inch, D-4inch, etc
