My mother in law just sent me a photo of my son dressed in a dress and with his hair tied up for fun. I am quite upset about it but my friends are telling me it's ok. Do you think it is wrong for her to do that?

I think it's a normal thing and cross dressing that most children do. Children would know by the time whether they are boys or girls. It is usual for preschool boys and girls to dress up in clothes of the other sex as a way of trying out what it is like to be a man or a woman, a father or a mother. Generally this kind of cross dressing does not last. It is part of all of the child's play activities, and not any more important to the child than other play. Cross dressing in play like this is a healthy way for young children to learn about and think about the world they live in.
