My kids do the same thing G. If they need something, even if they are at dad’s, they call me. He seems to have them convinced he can’t afford anything extra and that he is really stressed most of the time (some things never change) so they loathe to make him uncomfortable or put out in any way so it’s just easier to call mom. We the 50/50 custody though so there is no child support. We do, however, have an agreement that we split any extraordinary child expenses at the end of each month. Currently that is RESP’s, cell phone any extra sports fees. On occasion, an expensive pair of shoes. Does the child support he pays cover extra expenses? I know the child support that XH used to pay his daughter’s mom did not so we were always paying little extras here and there. Little G is a teenager now. Expenses are greater in a lot of ways. Maybe the child support payments can be increased to reflect that?
