When you're small, everything is new and delightful to you. Like playing endless games of peek-a-boo. Or seeing a dandelion for the first time.
Tom Fletcher - who you might recognise from McFly - posted this video of him and his adorable young son, Buzz, out for a walk in the countryside.
Tom stops to blow a dandelion clock and his kid's reaction is possibly the cutest thing we've ever seen.
That giggle! Those teeth!
Isn't that the most infectious laugh you've ever heard?
