[CO] custody advice

Hi everyone. I am currently 37 weeks and will be having my child in a couple weeks. Me and the child’s father are not together and don’t live together, but I am trying to figure out a co parenting schedule with him without having to involve the courts. He is wanting a week off week on type schedule (me 7 days and then him 7 days) but I am not comfortable with this while he is a baby. I don’t know how to word into nice terms without him getting upset that I am not ok with that schedule. Any tips would be helpful. I did mention that I’ll be breast feeding and that newborns feed a lot but he is saying that I can pump that way he can have our son overnight. Please help me out if you guys have any advice I want to avoid court because I can’t afford a lawyer but how likely is it going to be avoiding court when I tell him I’m not comfortable with this schedule?
