Custody

Ichigo • I have one daughter. I'm also pregnant with my second. Unmarried.
So my daughter's father and I get along really well, despite how we ended and the fact I'm still pretty annoyed he has a girlfriend. The other day he asked for partial custody, and I agreed because I understand why seeing ad though his parents are still going through custody battles with his little sister. We decided on switching every other week, starting when I go back to college. I'm still not a huge fan of courts and judges they freak me out. Can we do it by getting lawyers abd just signing papers?
