The Day Benjamin started sitting by himself

Here is another video clip.
I took this short video for a record of Benjamin's starting sitting by himself.
It happened to be the Halloween day (Oct. 31st), so he is wearing a halloween outfit (Little Pumpkin).

This is just when he started being able to support his upper body with his hands while sitting by himself, so his back is not upright yet --- at this point he could only sit upright for a moment or two.

About a week later, though, he started being able to sit upright for quite a long time --- more than 5 minutes at a time, and now he can sit and play by himself for a very long time very happily.^^
