Assuming this isin't from a troll: Any child that is just old enough to get her first training bra is
nowhere near old enough to be wearing a thong. There is a thread here about "my 12 yr. old wants a thong", search for it and you'll get plenty of input on the topic. Thongs and G-strings are meant to be sexually appealing underwear for women (see MontanaXVI's pic's). I don't even think there is such a thing as a "training bra/thong set" (and if there are, those companies should be taken to court!).
I barely had "mesquito bite" boobs when my Great-Grandma took me shopping for my first bra when I was 11 (I still have it 21 yrs. later BTW, in memory of her). I wasn't even aware of my budding breasts and detested having to wear that piece of clothing. I'm only 33, that should say something about how disdurbingly fast kids are growing up these days. They're just old enough to
possibly need a training bra, and a "thong" is included in that thought at the same time! Keep your daughter in her appropriate age group (with lessons, clothes, behavior etc.) as long as possible because she will grow up fast enough, you shouldn't want to add to any corruption that she might experience from outside sources growing up as a teenager.
God, I long for a child (since my first and only died 11 yrs. ago), and I can't ever see myself questioning something like this if and when I'm blessed with one. "Thong" won't even enter our discussions until she (he? That'll be different!
) is 18 yr's old. Just MHO.
