Mischief

For someone who doesn't crawl yet, Jack always seems to be busy with something, but he's usually smiling while he gets things done.

 Pulling the toys on the bouncer

 Showing off his gums

 Concentrating

 Making it hard to finish a diaper change

New stacking cups to play with.  He can sit on his own so the boppy is there just in case he decides to arch back and I can't catch his head fast enough.

 He's got multiple toys in reach

 Getting frustrated with them

He's got it and he won't let go!
