We haven't used the swing for Preston in probably a couple of months because he has gotten too big for it. We got it out for Gwenever to use while she was here, and he would go up to her and push it back and forth. He wanted to swing too. As soon as she got out of it, he tried to climb up into it.
So we let him swing it it.
He was so content, probably swung for a good 30 min or so and looked just like he did in that photo above.
