So I said I wouldn’t prattle on endlessly about my children – but I should mention that today has been one of painful milestones: first Colin, my easy-going and smiley little guy, burst into tears when I handed him over to the sitter this morning. Offical mom-is-a-heel moment as I slipped out the door. Then, tonight, he nipped my, well, nip. Little bugger chomped me but good – very ouch. Very.
