I have a few friends who do it. They are all older now though.
One of my friends & her ex went 50/50, week on, week off. They attend school 25 minutes from here, so she has to drive them 10 minutes to the bus when its her week. They were about 3 & 8 when they started. The youngest was 4 when I met them, so not sure if it started earlier than that or not, but her DS was BF til 3.5, so I assume he was with her mostly.
The other friends DS is 9 & is at the age where he chooses where he wants to be. Mum & dad live a block away from each other & get along ok. He'll be at his dad's for the week, then decide to go to mum's for the night & vice versa :lol:
I do agree that age is a big thing to think about.
