It's different these days, rolls have changed. I had to buy my own training bra and everything personal growing up with money I had earned. My Mum never talked about or discussed at all.

Fast forward to now, my brother is the SAHD while his wife works shifts. He takes his daughters to get pads, tampons and took her to get her first training bras just the other week. She has just turned 12.

The younger of his girls wear the crop tops while his older have just started on the training bras, it could be a good bonding experience for you to make a day of it. Go out, get fitted for a training bra, lunch, movies and maybe even get your nails done together. The more you make it a normal part of growing up the easier it may be (hopefully) for your DD not too mortified by it all
