My 13year old is going through a tough time. She has health problems / learning problems (dyslexic traits) / friend problems / family problems - (especially at her dads where she lives alternate weeks) - Dad calls me today to tell me DD slapped younger sister 11 (our other DD) around the face - when she refused to do a chore that stepmother had ask older one to ask younger one to do. How should i handle this? Relations are not great between houses. I've not heard the kids's sides yet and it wasn't witnessed by an adult. There are 2 other kids in that home too. 2 boys - whom i don't think were invoved. Thanks
