My ex & I have 50/50 custody and what was put in the papers as 50/50 placement but it's more like 75/25 placement.
This is our schedule (it's easier to see like this vs. just writing it out)
I also carry insurance for Rowan, and she goes to school in my school zone. I also bring her to the doctors, sign her up for school, etc but that's mainly because my ex is lazy. We switch years for claiming on taxes and things like clothes are bought for our home only so we're not fighting over the other having all the clothes, etc.
We allow each other to take Rowan longer on weekends that aren't our own if something comes up or to switch weekends when need be. Flexibility is key, IMO. There will be rough patches but with time it'll be a lot easier. Not very special holidays it's basically whoever has her sorta thing but big ones (like her birthday, Christmas, Easter we switch. One usually has her on Christmas Eve, the other on Christmas Day and on Easter/birthday, we split the day. We each get her on our birthdays and mothers/father's day.)
