You absolutely need to talk to her about everything that happened. She needs the opportunity to ask questions and to hearnyour reassurance that it's not her fault. I would start with the incident that got the RO in the first place, explaining how it was wrong for daddy to do that and the policeman told him not to come to the house. Tell her that he made another bad choice by bringing her home because the policeman told him not to do that. If you had not told on him (by calling the police) you would get in trouble yourself. Daddy was wrong to hit mommy and the police said so too. So there are some new rules we need to follow until daddy learns to behave properly. What he did was wrong and this is how the police think is best to keep mommy and you girls safe.
