Thanks to one very clever app.

Parents can now let their kids see exactly want Santa & Co get up to when they deliver the presents...

The app allows you to film a video of Santa's reindeer as they tuck into the plate of carrots you left out.

We wish this has been a thing when we were kids...

The clips look really realistic and are bound to have any child completely ecstatic.

The app comes courtesy of the folks at McDonald's.

The app was originally launched last year, but it went down so well that they decided to bring it back once again.

So, here's how it works:

Once you are on the site, all you have to do is take a photo from somewhere in your home.

It can be anywhere...

Whether it's outside or in the kitchen, it's completely up to you. Although we definitely recommend opting for beside the Christmas tree.

Then, this is where the magic truly happens...

Once you have your setting, you simply press play and watch your own personalized (and very adorable) Christmas scene unfold.

It's such a simple way for families to get into the festive spirit.
