I forgot to mention in last night's post Jack's new skill. For a couple weeks now, he's been waving bye-bye, but only after the person leaves the room. It's too funny, we beg him to wave bye-bye, but he just stares, then as soon as the person leaves, he's a waving machine.
BUT this weekend, he mastered his timing and now waves bye-bye on cue. It's a floppy arm wave, and we love it! I'll try to post a video of it soon.
