Joris found out about a month ago that some things fit inside other things. The cups he has in his hand on the left and the wooden car above are have been his favourite toys since then.

Joris is a little techy. What fits inside what? Small in big and not the other way around. How do you put tings on top of other things? It can keep him very well occupied.

He can sit by himself, but you have to stay near because Joris will let himself fall when he's had enough.

Joris can do a tiger crawl over the ground since half November. That means, among other things, that he can be naughty.
