Awesome, Gary!
I've had a few of these moments before, and like you I craved more. I found out, though, that forcing (not really the right word) more of these situations was counterproductive to actually getting them. In the end, I let the kids know that I was there for them, anytime, anywhere and simply cherished them when I got 'em. Don't beat yourself up too much for "not being attentive enough". I think you're doing a marvelous job!
