That's funny... that's us. Both my kids preferred opposite gender playmates when they were a bit younger. Now that they're 10 and 11 this has normalized greatly and DD has her girl "besties" and DS has his male buddies. When I was young I was a tomboy who preferred playing with boys and had a hard time connecting with the girls - I just found them too... I don't know... "fluffy." Now that I've had kids I can connect with other women much more easily via motherhood.
