Children who have to live through their parent's divorce might find it hard to cope with what is going on. Some might wonder whether their parents splitting up is their fault. The little ones might think that they did something bad that made it happen. The older ones might assume that their behavior or performance in school has a part in the adult calling it quits. One of the most important things that you can do in these cases is to reassure the children that they didn't play a part in your divorce. You might have to do this multiple times, so be ready when you notice it is needed.
It is also possible that kids will think that your divorce means they won't be able to spend time with one parent. This isn't something that you can talk them through, but making sure both parents are able to spend time with them can be beneficial. You should be sure that you keep up your end of the parenting agreement so that the children know they can count on you.
Children might also think that your marriage can be saved or brought back together if they behave and try to get you and your ex together. Remind them again that they weren't the cause. You should also be prepared for them to try to sabotage any new relationship you get into. This is a good chance to remind them that divorce is permanent and that you aren't getting back with your ex.
Throughout the divorce and the adjustment period, you should reassure your children that both parents love them. Make the most of the time you have together so that you can make good memories during this tumultuous time.
