Yep -- this is his new game that he plays with himself... holding his breath!
This game seems to have replaced the rolling over game, as he hasn't done that in a while. He is also starting to demand to sit up at times,which is funny, as currently, I can balance him for about 2 seconds before he topples over. So, I found a short term remedy --
Looks like I got him mid-blink! Ah, well, he's still so very, very cute.
