Most parents don't have to deal with only having their children for a few hours per week, but there are some who still do have to cope with this. The situation isn't ideal for either the parent or the child, but it is important to make the most of the situation so that you can enjoy a meaningful relationship with the children.
One of the most important things to remember is that you don't always have to go do something grandiose or expensive when you do have the children. Instead, you can spend quiet time with your child sometimes. The important thing is that you are spending time together. It might be appropriate for you your kid to have a heart-to-heart talk about matters so you can find out if there are any concerns they have or things they need to address.
Another important point is that you can set traditions based on the time you do have with your children. You might not get every holiday with them, but you can set up traditions for the days you do have around the holiday.
You set the tone for the time you have with your children. Go into each visit with them with a positive attitude. Let them know that you cherish the time you have with them. Even if your child isn't in the best of moods, you can try to turn that around by showing them love during the visit.
Because both parents are important in a child's life, you should always make an effort to spend your parenting time with the children. If something unavoidable happens and you can't do the visit, follow the rules set by the parenting plan. You might be able to reschedule the time so that you can still enjoy them.
