From about 4, son went to his dad’s for a weekend, which was enough for each of them I think. It extended gradually to a long weekend and now a week at Xmas, Easter & in the summer. Son goes to holiday club for three weeks in the summer, and I take 2 weeks off.
The rest of the year, ex prefers to see son on a Sunday but not overnight.
we’ve managed to keep it reasonably amicable, and flex around each other’s lives.
I know the courts prefer EOW or even 50;50 but you have to do what works for you both. You’ve got 17 years of co-parenting to survive so you both need to be comfortable with any arrangements.
My ex and I have alternative Christmas’s, one Christmas I have him Christmas eve until lunchtime Christmas day and she has him the same the following year, it seemed the only way that was fair, after Christmas eve/ morning is magical for children so it’s great that both parents can enjoy with the children.
We also do alternative New years eve so both get the chance to go out if we want.
