That is a reality. The normal parental relatioship is changed. We can all it whatever we want, co parenting, parenting time, but the reality is that it becomes a situation where both parents have to have permission to visit their own child when the other parent has them. You can actually spend more time with your nieces and nephews than you can with your own children. It is a situation where you can be escoted away, by the police, for trying to visit your own child. It is not better than when you had normal parental access.
So the reality exists, and the only thing you can do is make the best of it, which means you can co parent as much as possible, make decisiosn as two parents, allow more time, as much as you want, overnights, that is up to the parents involved. No matter what, a child being forced to spend less time with a parent is not a good thing. That is the default. There are always the instances where a child is better off spending less time with one parent, but that is not the norm, there are bad parents, that is not the norm.
What ends up happening is that hopefully you make the best of a worse situation, it is not as good, but it doesn't mean it has to be the absolute worst, or the kids will be deficient in some manner. But it is never better than the norm. You have to work with it, and you can make it work, but I don't see how a loving, caring parent being restricted is equal or better for a child.....
