Aldous learned how to sit up quite well and can do so on pretty much any kind of surface. He only tends to fall over when he's reaching for something. He's also learned how to get onto all fours and rock back and forth. As soon as he figures out how to move, he's going to be gone!
Aldo loves watching his brother and if you need Aldo to laugh, Eliel can get him to to it just about every time. Eliel loves to have Aldo 'watch' him play but hopefully soon they'll be able to play together!
