I think it safe to say that her kids kept her strong, kept her from "clawing at the fence" as it says in InTouch. I think that the bond between them is stronger than even a normal mother-child bond. They were her reason to make it out. As far as the kids go, I have not a worry, except for the worry about the problems caused by having to tell them that she is their mother, not their sister. But, considering the ages of the girls, it is probably just confirming a suspicion they already had.
