My tips for co-parenting with a long distance parent is establishing a really strong form of communication from the very beginning. You have to set up plans for when the child is going to travel, who is going to be there, how long are they going to be there, how much it is going to cost, and are they going to keep the child on the same sleep schedule. The next thing that is important to do to keep the lines of communication open between the child and the other parent is to make sure that you are setting up things such as, Skype. A normal, consistent Skype call, so that the child has time with the other parent to see them face to face. Another thing, especially if the child is younger, is letter writing since that is something they are already doing in school and you can never have enough practice writing. It is always good to have the child write weekly letters to their other parent and have the other parent respond. It's just a really good way to keep them close and for the child to have something tangible from the other parent.
