WOW....mommy2006. if your daughter hasnt already I would imagine that she will be getting her period soon, and wearing a bra. I think there were about 3 characters that would be ok for her age....older girls fancy hello kitty and Kim posible and sometimes Pooh.But the others are only for little girls. buy her plane undies, if your against older looking ones. and keep in mind mom that that site is called potty training concepts.
A healthy compramise may be for you to only buy what you are compfortable with her wearing and allow her to put her own outfits together. I do this with my 10 year old to encourage self esteem. There have been times when I have had to oppose and make her change but all in all it works out well, being that I am the one who makes the purchases.
