It wasn't that long ago that Benjamin reached the milestone of sitting up by himself; but as it turned out, he suddenly got in a rush and jumped ahead to the next milestone. Eight days after the sitting-up milestone, Benjamin pulled himself up to a standing position for the first time!
It happened yesterday while Benjamin was playing with some toys in his room as I did some work in the other rooms upstairs. I was going in and out of my room (which adjoins his) and "happened" to go into my room and stand by my dresser, from which I had a diagonal view right into his room, at the precise moment that Benjamin grabbed hold of the side of this brown cube and managed to hoist himself up into a standing position.
Very, very loved.
