Parents who are going through a divorce have to quickly decide that they are going to work as a team. Trying to fight against each other in matters about the children can set a difficult precedent about how the future of the parenting relationship is going to go. One of the most important things that you need to do at this point is to remember that your children are perceptive. They probably know what is going on.
It might help your children to speak to you and your ex together, so they can get their questions answered with both parents together. This is a time to tell them what is going to happen and to reassure them that they didn't cause the divorce. When you are speaking to them, don't make promises that you can't keep. Only let them know things that you know for sure, and don't be afraid to say you don't know the answer to something.
As one of the cornerstones of your child's life, your attitude can set the standard for their life. If you have a positive outlook and remember that they are looking up to you, things might fare better for them. Work on setting up an environment in your home where the kids can thrive. Set new traditions and make amazing memories with them.
You will have to work out the parenting plan and set up other aspects of the divorce. If you and your ex can work together instead of battling about everything, you might be able to keep the cost of the divorce down. This can also benefit your children because you can shift the funds you saved toward keeping up with the standard of living your kids are accustomed to.
