No problem...just make sure you have a paper trail of each payment you make to her or a reciept showing you did. MAKE sure it is in HER handwriting. She can then not say you missed payments and have you thrown in jail. If she claims you missed a payment the state can take over. This means you send payment to them and they forward it to her. NO DEAL you to make can supercied a court order.

In texas all payments go through the state and the charge 5 dollars each. This is a HUGE revenue builder for them. You state may have similar.

If you get a gut feeling the mediator is favoring her..then becareful.

As for some advice from others...in some states the child can make a choice which parent they want to stay with. This on the norm is 14 to 15 yrs of age or higher. Some maybe be lower, i don't know. In most cases children want to stay with the parent who lets them get away with the most. Do not let your kids pit you two against each other...you will know if this is happening.
"Mom grounds me when i make a D, i want to go live with dad"
"Dad make me do dishes and mow the yard, I want to move in with mom"

You two also need to think which of you live in the better school district...this is very important. If your kids are good at sports, which school might they be able to make first string. Getting them into a college with scholarships for anything they excel in could be far more than the total of child support you could ever pay.

Always think of the big picture ! Now-a-days it is very hard to get any job that allows for a comfortable living without some type of degree. Every parent should want their kids to have a better life then they did.

Some states can mandate you pay CS for 4 yrs past high school graduation if they are attending college. BEFORE signing anything from a mediator..ask to take the paperwork home to read it over in peace and quiet. They should not object unless they fear you catching a certian wording. This can give you a chance to have legal counsel or a knowledgable person read it over. Once you sign anything it is a done deal and will take a lot to get it changed.
