Reading the last few comments reminded me of that photo of toddler Zero in diapers standing on a walkway next to a cottage with a large outdoor sink attached to it, and a typical Hawaiian landscape plant. I remember we discussed that photo and having lived in HI, I recognized that type of beach shack/cottage well. Of course such dwellings could be from other place as well, but the plant and dwelling and that sink (I’ve washed clothes in a sink just like that in HI) really look like HI.
He looks to be about - just under 2? in that photo? Or about 2? I wonder.
The one you remember is the same as the image of him sitting on the step, taken on the same day, obviously.
That's the image in that composite I use to show he's the same child as the boy on the left in the two little boys image:
