We agreed to split Winnie's health insurance, school and medical costs. We did not agree to split all extracurricular activities. These expectations were never discussed. To avoid future confusion, it is best that we create an official parenting plan on which we can both agree. We can do this with a mediator if that makes you feel more comfortable. A parenting plan includes the following: Parenting time, holiday schedule, medical decisions and payments, school decisions and payments, Extra-curricular activities and child federal tax deductions. It seems we agree on all aspects with the exception of the extracurricular activities. I am willing to pay for the activities I sign her up for.
