Seen baby today! Gender?

Kristen

11w 5d and baby was waving at big sister! Kicking, wiggling, sooo active and happy in there! With my little girl I just knew she was going to be a girl. I want another girl, but I’ll be over the moon with either. But I feel like I may have a boy this time. Theories? I don’t know how you all do any of them! Lol!
