This is one of my conversations with Duncan from this past week (keeping in mind that all his r's and l's still sound like w's):
D: Mommy, Duncan need change my diaper!
W: Let's change you then.
D: I need cream for my bum.
W: Ok then, go and get it.
D: (looking all serious and concerned as he walks back to me, cream in hand) It has a crack!!
W: What has a crack?
D: My bum!!
W: It's ok, everbody's bums have cracks, there's nothing to be alarmed about!
D: (very skeptical) Noah's bum have a crack?
And then he had to ask about pretty much everyone else he knows. Two is my favourite age. I'll take a few screaming fits to have conversations like these any time.
