Negotiating a child custody arrangement isn't an easy task for some parents. This is often the case when the divorce is contentious. Making it through this process is going to take effort on the part of both parents.
One of the most important things to remember is that you have to focus on what's best for the kids when you are trying to work out the parenting plan terms. When you find that the conversation is veering away from this, you can try to get things back on track by thinking about how each decision you make will impact the kids.
