I had this vision that the Bjorn would be the sole province of Dad, and that Henry and I would use the Baby Bjorn all the time. (Secretly, I hoped that I could use it to play video games while he slept.)
Henry does love his Bjorn...

...and he often falls asleep in it...

...but he only sleeps as long as he's moving, so you've got to keep walking. And, to be honest, he prefers that you have a little bounce to your walk, so you'd best hop to it.
Also, it turns out that he now only likes his Bjorn; Now that he's used to seeing the world when he's out and about, he's spoiled, and neither Mom nor Dad can get him to stay in his stroller.
Daily walks in the Bjorn are now required.
