My daughter is 10 and she has begun her menstrual cycle..and we all know the joys of the hormonal changes that come along with that. But I have to say that the attitude my daughter has just makes me cringe to the point of locking her in her room during her cycle! Shes just downright mean to her little brother too, I have talked to her about her mood swings and how she needs to try and keep them on a leash lol but she lets them get the best of her. I just can't believe my only girl is going through this and getting boobs too omg its just too soon!!
