Feeding the reindeer must be something new. The grandson goes to preschool & he had everything set up for Santa the cookies & milk along with reindeer food. It was a mixture of oatmeal & he left that out for the reindeer. They mixed it up at preschool & got to take it home. There backpacks must have been loaded down with reindeer food. Some of the backpacks are bigger then the kids wearing them too.
