Today, she was munching on cereal and the incisor took a big tumble forward -- but still refused to come out. This concerned her so greatly that she refused to go to the swimming pool this afternoon, for fear that the tooth would come out in the pool and be lost.
So I got some dental floss and slid it behind the tooth. Just a little bit of back and forth and out came the tooth.
It is now waiting on Katie's nightstand for the Tooth Fairy to arrive tonight. :)
