Check this out. Liam's basically running in his jumper.
It's bordering on dangerous. If he gets any more distance we may have to take the jumper down. Or probably move things out of the way to give him more space to run. Because man, he loves it. You wouldn't know it from watching, but he was sick yesterday (when the video was taken). Snot pouring out of his nose and all that sort of stuff. But put that kid in his jumper and it doesn't matter. He's happy as a pig in mud.
By the way, the song is Cake's version of Mahna Mahna with audio tweaking by yours truly. It will be stuck in your head for the remainder of the day. You're welcome.
