Make a list of things that you want for your 7 yr. old and yourself. Such as: Holidays and special days that you want to have your child, i.e. Christmas, Thanksgiving, Mothers day, your kids birthday, etc. During mediation they will go over everything like this including what time of which day they will be picked up and what time on what day they will be returned. Both you and your ex will have to work out EVERY detail of custody and other various issues, and when it is all over you both will have to sign papers saying that you will both abide by EVERYTHING that was worked out. When the mediator sends this to the Judge, he will most likely sign it and it becomes a court order. You will both have to abide by it to the letter and the only way to change it will be to go back to court & start over again to alter the court order. Be sure what you would 'give and take' with your ex-spouse so that it is reasonable, but above all else: What is in the childs best interest. THAT is what the judge will be looking at, so try your best to subdue your emotional involvement and any anger and think clearly about what is BEST for your child, not you and your ex.
