What do you agree on?
Communication is key to co-parenting, so it is important to get things together. For example, you discuss:
the division of tasks between parents. Who does what?
the living distance between the two households. Can you just move to another city?
the overarching rules. What is the latest bedtime?
discussing important things and changes (such as choice of school, vacation arrangements or relocations);
birthdays and holidays;
the finances. Who pays for what? And do you keep a cost book?
