Should I let My baby's father take him out?

He threatened to take your son away and now he expects you to just let you walk out of the house with him? Yeah RIGHT! You were more than accomodating in allowing him to come visit his son at your house to establish a bond and a level of trust first. Document everything - facebook convo's, emails, write down the wording of any phone calls and their dates and times, and any personal encounters as well. Based on the threats of this boy and his new girlfriend I'd definately request supervised visitation but you need to have a record to show WHY you want it supervised. Start keeping a journal of just your contacts with him and the gf.
