When Connor comes up to me sucking his thumb, his orange blanky lagging behind and says, "I need some lovins, Mommy." I'll look into his eyes, and he flashes me the cutest little grin you've ever seen.
And, because he may very well be our last, I take him up on it every chance that I can get!
Seriously, it's the best thing ever. I don't want this kid to ever grow up.
