I took these the next morning before school. I woke him up, and asked, "Xavier! Where's your tooth?!" He put his finger in his mouth right away, pushed his tongue against where the tooth should have been and got this huge grin on his face. It was re-played just like that at school when he was showing off his MIA tooth-status to his entourage.
(My apologies to the sissies who are grossed out by the 'tooth funeral' picture below. )
He loves it!
