Take care of yourself
Eat Healthy: Being in the hospital will mean yo are eating hospital food. You might be tempted to eat the comfort food. you need healthy foods. You need to be eating meals (don't forget about breakfast)
Exercise: I know, in your spare time you are going to find time to exercise. . . but it is true. You really do need to find a way to exercise. It does Help.
Get Away from the hospital: I know that you want to be with your child all of the time, but you have to get away from the hospital. A friend of mine who recently spent months in the PICU with her infant child who was undergoing heart procedures wrote this article for Prevention Magazine . For her husband, he healed hiking through the nearby mountains. For her, she healed in the pool. . . . and at the mall. . .
You have to keep yourself healthy.
