How long do i have to wait to go back to fcs for modification or to enforce orders made on previous fcs mediation meeting?

I went to mediation earlier this year with my ex wife. One of the agreements was that i call my son every night at 6:00 pm for a qick good night. She does not make him available to me. I would say i talk to him 1-2 times a week. I went to my counties fassilitator and was adv to go back to fcs since the specific time was not added on or summaries. I did just that and had her served. She now got an attorney and is suing me for attorney fees. She is saying it is too soon to go back to fcs, only 3 months after and she doesn't want to go back. She is also asking that judje order me not to serve her again unless it is an emergency. Can she do this? She also said she doesn't want me to call my son daily she wants me to call him no more that 3 days a week. wouldn't that require we go back to fcs?
