My child with my ex is 13. I have remarried and have 3 other children that my 13yr old babysits for occasionally. I returned to work part-time. Usually it is for 1-2 hrs but one day it eneded up being 4 hrs. My ex threatened to call the police and said it is illegal to have a 13 responsible for other children. I need to be free of this man's threats to take custody away from me and have been dealing with this for 13 yrs. Can someone please tell me what the law is, so I can be clear and take a course of action. Thank you. I live in NH
