I think Big Mac's reached a point where he has enough neck and upper torso control for the Bumbo Chair...which I so appreciate, since he would rather be sitting up (or standing, for that matter) than any other position. And Maclin's not shy about telling you what he wants.
Look at my big man! Seen here with Sophie The Giraffe, his toy that I bought during a middle of the night feeding.
Amazon makes impulse shopping WAAAY too easy.
Here's a photo I found from August 5th, when he was clearly not quite ready for his chair.
Yes, much better now.
