I pay full child support etc and my 3 school age kids between 6 and 11yrs go to their mother's after school for 1.5 to 2 hours during my week as she is not working. We have a shared parenting arrangement. She is now requesting payment for this and will provide receipts? I have offered to pay for any additional costs associated with after school care during my week such as snacks and am not aware of any additional costs associated with this arrangment. Is this right? they are her children and she gets to spend extra time with them and they get to see her more which is good as well.
