After we separated I had 3 kids full time for around 3-4 weeks while he was house hunting (moved into his mates in the mean time). Once he had a house, he had them 6 days/overnight a fortnight. That lasted about 5 months. I was then having issues and he had them 11 nights a fortnight and I took them 1 at a time for 3 nights. Then our agreement changed to something more complicated we all got confused.

Thankfully we now do week on, week off.

I'm friends with my ex so we speak every week at change over, and communicate as needed through out the week.

Birthdays we all meet up as a family (+ our own hubby/wife) and celebrate. Christmas I have them on odd years and Easter on even years.

Anything at the school (merit awards, interviews etc), we both go together.

We get in much better now and support our children the best we can despite being separated.
