As unfair as it may seem, (I'm not sure from your user name your gender), however the mother generally is awarded interim custody which turns into full custody unless otherwise demonstrated. Since you are unable to mediate, I'd venture to state that shared parenting would not fly as you would have to have a certain level of communication and give-and-take in order to be awarded such.
I would seek full liberal access, every week if you are close enough, or alternating weeks with 50% of all school scheduled holidays, your birthday, alternating birthdays for the child, (or shared) and a Claus for extended/unexpected access for, but not limited to things like anniversaries, family reunions, weddings, extended family birthdays, or special events etc.
If I could turn back the clock, I would have had my husband seek to have all access clearly defined in the first motion as it felt like she was nit picking way through the issues. There always was some issue that the courts left for “the parties to mediate” and come to an agreement on, on their own. Had we been thinking, having it all resolved from pre-school to full time school etc, we would have saved a lot of emotional upset for all involved not to mention travel and court costs and lost work.
