Here are the last two videos.
This first one is Ben practicing his sitting in his giraffe costume.
Last, but most definitely not least, Ben just picked this one up today. Jon was beat-boxing to him in the basement and Ben started shaking his head along. I wouldn't call it sophisticated dancing, but I would call it dancing and it's stinking adorable. If you don't believe me see for yourself:
*Note, it's hard to hear, but Jon is beat-boxing, not just shaking his head. Also, Ben did the same dance to some music we played as well.
Also, I should mention that I've become quite proficient at typing with one hand while I hold Ben in the other. Does anyone know if that's a marketable skill?
