Not so crazy about the "two front teeth" version, though.
Never heard of those in the list.
However I do smile when hearing the “two front teeth” one.
Our kiddo lost her two front teeth in one of those weird mama intuition moments with me running out to say don’t do that but was too late by a split second. Blood was everywhere but what she cried about was the Tooth Fairy wouldn’t come because the teeth were lost at the bottom of the river. That happened during the summer and there was no sign of new teeth at Christmas break. One evening, she visited Santa and told him she wanted her two front teeth for Christmas. The next morning both new front teeth were halfway in.
