My ex and I share one infant age child
recently ex has started having our child overnights more, so cms will be reduced
historically I have paid for all clubs (dance, swimming lessons), school uniform, trips, childcare related costs etc
ex has bought 2 pairs of school shoes
my argument is that as cms is reducing due to ex having more time, he should contribute more to the above costs of clubs etc
he disagrees
my thought process is that surely if he is taking more time and assuming more responsibility for our child he should pay proportionately into those costs, they shouldn't sit solely with me anymore
