My daughter assumed we would look after her kids, ages 9 and 7, five days a week. She became upset when we were told it was too much for us. So, out of anger, she told us that we cannot visit them anymore. Our daughter has always been very stubborn. I know we will ultimately have to listen to her demands. But I and my husband are physically not so strong as to deal with two energetic kids anymore. I do not know how to deal with this. She is our only child, I cannot let her remain angry with me.
