Financial support from child's father

Marie • Hello, my name is Marie, I'm 27 years old and I joined this website the moment I found out that I was pregnant. This is my first pregnancy and I'm praying for a 100% healthy baby boy or girl 😊
Me and my son's father is no longer together.. Haven't been since my 3rd trimester of pregnancy and my son is now almost 2 months. He has not gotten him anything except for wipes. Before I put him on child support I am willing to work with him on how much he should give me weekly. How much is a good amount per week for an infant?
