I see my young son has some curiosity over hes young baby sister. My husband told me he saw our son put hes sister's hands between hes legs. Yesterday i saw my son laying on top of her (no activity) just laying there and she was laughing. My son is 5 and hes sister is 1. I have been molested before and my mother sis nothing about it. I don't know how to Handel this situation... if my son gets older (16+) and does something bad to hes sister ......... my son or not.... i will call the police and get him some help. How can i prevent this... How to start off the conversation???
