What are your custody arrangements?

As some lost i made before I have a 4 yr old and a 1.5 yr old. And baby on the way. Right now there are supervised visits until March when we go back to court and talk about how things are going. The father and I dont get along. Hes a narcissist and emotionally abusive. So its hard to have any reason with him.

Could you guys tell me what your custody agreement is? Who determined it? When did overnights happen? And how did you get through it having your children not home overnight that young??
