Santa's job is no joke. First, he's got to decide on the perfect presents for your kiddos. I bet he does a lot of research on where his elves can find things cheapest. I mean, they can't make everything these days and there's no way his budget can support full-price toys for everyone!
Then, he's got to keep track of all this naughty or nice business. Santa probably has hundreds of thousands of Elves on the Shelves reporting in to him every night. It's amazing he can keep track of which Elf belongs to which kid, they all look so much alike! He's also got to make sure that each Elf gets back to his or her respective home and remind them to hide in a new place every night, a place where little hands won't touch them and make them lose their magic.
And all that wrapping! Somehow Santa needs to know what wrapping paper each Mommy and Daddy are using so he can wrap in different paper. He also has to come up with things for the stockings. It's probably especially challenging for him to come up with stuff for Mommies and Daddies, and sometimes he goes a little light on them because there are just so. many. kids.
Don't even get him started on the endless public appearances. Between the parades, and the trains, and the malls, and the fire trucks it amazing he can find time to do anything, nevermind sleep. Honestly, cookies and milk isn't the best fuel, either.
Phew, that seems pretty tiring to me. I'll tell you what though, the smiles and laughs and joy from my Little Man alone is probably fuel enough for him to get everything done with energy left over!
