I don't think it helps to have a big sitdown about the whys of dressing to young kids. You like to dressup and look pretty,mommy likes it too and you go out and have fun and enjoy it....enough said. And with most kids,if it is ok with Mom,it is ok with them! A sitdown talk might stick in their minds and become"news" to tell their friends and teachers.lol Last year when my then 7 yr old daughter was asked at school about family hobbies,she told them that her Dad collects tights and has lots and lots of them!! :D
