Our son is soon to be 4 and he is constantly dressing up in his older sister's (5 1/2 yrs) dress up clothes, ballet outfits, etc and prancing around. He prefers to watch"girl" movies with princesses in them. When asked, he knows he is a boy, but he's not real excited about it.He doesn't particularly care for boy toys either. He is surrounded by girls his age and his sister's age and he doesn't really have many boys his age he plays with besides at mother's day out a couple times a week. What type approach do you recommend in dealing with this so he had a healthy understandingof his masculinity?
