Alex is getting closer and closer to being able to sit up on his own. If you don't hold him in place he can stay upright for 5 or 10 seconds pretty consistently, but with the help of the Bumbo seat he can sit on his own all day:

Amazingly, Evan still kinda fits in the Bumbo, despite the fact that he's a little more than twice as big as Alex.
