They may both still be under 5, but Neil Patrick Harris' kids Gideon and Harper have already established themselves as celebs in their own right—thanks to their dad's considerable popularity, his massive Instagram following and their own tendency to be utterly adorable in each and every photo.
If you need some evidence, we're happy to provide you with it.
Here's Harper, getting her princess-fairy-thing on at her vanity (which NPH says she's glued to).
And here she is again with Gideon and dad David Burtka, just lounging on the couch adorably.
And, of course, let us not forget how this family does Halloween.
While they trimmed the tree, Harper and Gideon did their best to remember all the lyrics to "Jingle Bells" (hey, it's hard), as their proud dad captured it all on camera. The resulting footage is so sweet, it's already nabbed over 100,000 likes.
