What is the name of your state? Pennsylvania I need to know what the law is in regards to a minor child contacting his father via phone/ mail; My son is 5 years old and I let him call his father and write him letters when ever he ask.. well now the fathers new girlfriend told me that I could not send letters there or have my son call the house!! I do not ask to speak with his father at all , I dial the number and then give the phone to him and he ask for his daddy and if he is not there he leaves a message, now she is saying that she will have the number changed if I still let him call. Is this breaking a law by letting my son call and write and also does he have to give me a phone number so that his son can call or in cause of an emergency???
