Joan,
It sounds to me that those kids NEED you. A kid who does not want to go home for Christmas Eve, or Christmas morning, must not have a good home life. What about their parents? Didn't they call to have their kids come home?
I got a good laugh about the 4 month old. She doesn't know what day it is and I'll bet her mom and dad are sleep deprived and found a solution for at least one night! Thank goodness for Grandma!
