We've been chatting a lot with Isaac about potty training. To get him hyped up about it, we ask very excitedly, "Isaac, are you ready to potty train?!" He of course usually dances around on his toes and says, "Oh yes! It will be very fun!"
Yesterday, he was sitting in a cardboard box. I asked him what he was doing. His response? "I'm riding the potty train mommy! Choo choo!"
