I am a divorced mother of a 11yr old boy. My son, is an asthmatic and is in Special ed. At school. My ex husband refuses to pay half of the expense for a babysitter or daycare on Spring vacation and in summer due to my sons age. Also in my divorce agreement it states that he is to pay half of any day care expense. Doesn't "day care" expense include a babysitter for when I have to work? Please give me some guidance on this.
