An infant is most often viewed by the courts as better off with the mom, dad getting one or two nights a week (and I mean 2-3 hour increments, not over nights). If the child is over 2, say almost 3 ask for the reduction to, say Tues and Thurs over night and every other Friday to Monday morning. See if she will go with all elections (share holidaysw, 30 days in summer, etc based on the minimum guidelines of your state laws). This will actually give you MORE than 50%, just not in the perfect way. Give and take and have a back up plan/alternative to choose.
