For whatever the reason, Sophia just doesn't like the idea of her teeth falling out. I think she's got some fear that she's going to swallow it or something. On the other hand - she loves the reward!
I'm very thankful that it didn't fall out during Mass - so as not to involve everyone with the dramatics! I even envisioned Father stopping Mass to help the screaming flailing child who had... just lost a tooth! And I'm thankful that when it did fall out during dinner she happily informed me, "My tooth came out." And we put it in her tissue pocket and put it in her skirt pocket. She turned out to be a real trooper about it! Praise God!
