I have one child who has been sleeping since about 8. I don't expect to be disturbed by this child until morning (but maybe very early morning.)
I have another child who hasn't gone to sleep yet (it's almost 11.) One problem or another seems to be keeping this child awake and crying. I expect that this child will keep me from going to sleep for awhile longer and probably will have me up early in the morning. This child is two.
