I agree with Mel on the principal point. As parents we must do what is best for the kids and I agree that 10 days between seeing the other parent is too long.
IF (and that is a big IF), you and W can agree to PUT the kids interest FIRST, then I am and will continue to be a proponent of a "flexible parenting plan with a default schedule". That said, in order for a flexible schedule to work, both parent have to be able to communicate and are both willing to share in the responsibility of raising the kids.
At the end of the day, IMO, mom's have a much harder time giving up the control. It is the way our society has been established and although things are changing...the presumption more often than not is that the kids should be with mom more.
Scorp, if you feel that moving is best for the kids, then move. Sometimes in life ya need to give a little to get a little.
Whatever you decide to do, try and keep the kids out of it. Try to avoid from putting them in the middle of a heated court battle. It does them no good and only creates more resentment between you and your W.
There are many ways to skin a cat - whatever you do..make sure YOU are doing what is best for the kids (which I think is Melissa key point). Do not make this about 50/50 per se. Make it about THEM.
In time, they will make their own choices and you and your W actions during this time will IMO, play a role in whatever they decide to do in the future.
