Birthday Update

We are still struggling with Sam and toilet training, as in he blatantly refuses to use the potty, toilet, go without a diaper, or even discuss the possibility.  With the arrival of the baby, we decided to hold off on pushing the issue.  Recently he has taken to promising us that he will go when he is a "bigger boy," or after he turns three.  Well, his third birthday arrived and inevitably, as we wished him happy birthday and discussed breakfast Sam said,
"do I have to wear underwear today?"
Chris and I looked at each other.
Dumbly I asked, "Are you ready to wear underwear?"
"No."
"Well, then you can wear diapers today and when you're ready you can wear underwear."
He contemplated this and then told us, "I'll be ready on my next birthday."
We assured him he'd feel ready before his next birthday, way before.
