My son is 17 and his girlfriend is about 7 months along. her parents told my wife this evening they expect my son to pay approx $400.00/month in child support. I have checked the child support calculator for my state and at the very worst it suggests only $50.00 per month. My son is being a stand up guy but I think the girls parents are asking a bit much for a high school senior who is pursuing a part time job at this time. Any help would be appreciated
