The biggest thing for you to remember is that you must represent to the court your willingness to be a presence in your children's lives.
The court's have become much more Dad friendly, thank God. The avg Dad only sees his kids 4 days a month, every other weekend. Even though our lifestyle is a lot more dynamic, you have to sell that judge on how GREAT it is that you have the ability to see your kids 12-15 days a month! You can drop them off and pick them up from school, take them to practice, help with homework, make breakfast, lunch and dinner! Pilots are Superdads in a way that the avg Joe (no offense) can never be because of the precious free TIME you have to offer your kids.
We sold this idea to the court and won 8 nights a month, which was great for everyone except psychomom. Just remember, the court (judge) and your atty assumes the avg Joe schedule. You have to paint a picture for them each time you sit down of all the QT those kids will get. You have to keep reminding them!
Warning: Our schedule varies from month to month, which psychomoms like to paint as a negative. "The kids won't be on a schedule!" You have to be prepared with a gameplan.
Ours was to go to court with a calendar. We presented the plan to the judge as a suggestion of how the kids would know what the plan would be weeks in advance. Each parent was required to mark the special days of the year that they wished to spend with the kids IN ADVANCE. The days that were duplicated were split every other year, and extra special days to be negotiated later. You should have seen Sateena's face. The judge LOVED it! Judges LOVE when someone comes in with a calm reasonable plan so that they don't have to make the hard choices and be the bad guy!
Last, you must fulfill your rights to visitation. If she goes back to court saying you never see the kids or do what you say you will do, the judge could revise the order. Also document methodically and thoroughly Everything you and your ex discuss, no matter how small, with date, time, and content written in a log. Also document everything negative your kids repeat, and never ever say anything negative about her or let them overhear you saying something. You will have a lot more credibility in court with a written log than just "she said...."
Good luck. And remember that for your kids to be normal later in life the need to be able to love you both unconditionally now. Don't take away their joy of their Mother and don't let her do that to you. Even if she is Satan's Mistress.
