My lil one is 9 going on 10 her mom doesn't want me to bring her home with me yet.

My lil baby is 9 months going on 10 this month I'm going back to court this Thursday to try to get more custody I would love to get 50/50 but don't think that's going to happen. How much time would it be ok to ask for and the judge would say its ok with. I'm just tired of meeting up with her at stores because I really don't get to see her crawl or do anything with her all I could do is hug her as much as I can and let her know that I love her and no matter what I'm going to keep fighting for her but then she wants to turn around and just look at everything and everybody.
