Unlike his brother, David-Benjamin, Isaac is a willing camera ham. The instant you point your lens at him, he smiles broadly and happily, saying, "Cheeeeeeeese!" in a long, drawn out, genuinely pleased fashion.

Isaac is also one of the most flexible and foldable little boys I've seen, fearless and innocent, climbing atop slippery rocks to perch himself precariously. He's happy to explore.

And of course, who can ignore that winning smile?
