I have a friend who has almost 4 year old triplets -- 2 boys and a girl. The thread about the boy wearing the Cinderella dress made me bring this up. Anyway, one of her boys is always wanting to wear his sister's clothes. He says he wants to be a girl, pink is his favorite color, etc. He is her most challenging of the three, constantly testing her, pitching fits, getting into things he shouldn't -- an all around strong willed kid. She has put her foot down on him wearing the clothes when her husband is home or if they are going out. She plans on bringing it up to their pediatrician when they go for their next appt because this has been going on for several months. My opinion is that he shouldn't be allowed to wear the clothes because they aren't his; the fact that they are girl clothes I don't see an issue with. Being a multiple, they have to share alot; they shouldn't have to share clothes. What do you think?
