Well reading these posts really made me feel better because I have been feeling so guilty for the way I feel towards my step daughter. I'm not the only one with this problem! I have been with my husband for 3 years we have 3 kids his daughter that's 10 and his son that 4 and my daughter that 7. It started out we would have his on the weekends and at first she(his 10 year old now met her at 8 years) was very very sweet but if she did not get her way she would become intolerable physical throwing herself on the floor screaming as loud as she could until her dad gave in so she would stop.
