Is 350 for child support fair?

I asked for 400 but he says 350 is fair. He says he doesnt earn much. Though he told me when we first started dating that he did. 350 is no where close to all the things iv paid for and my parents have. i have even offered to share his things i got him with him so he doesnt have to buy more. but he says he wants to. well at least he says he'll put him on his insurance and put his name on the birth certificate. I guess I have no choice but if i were to go to court, would they give me more for him?? thanks
