Thane lost his first tooth today at 6 years, 4 months, and one week old. I have been dreading this for a long time as he doesn't handle change well. It was indeed traumatic, but we seem to have solved the problem within about 10 minutes. We made a note asking the Tooth Fairy to return the tooth so he can put it in his keepsake box. Otherwise he says he will miss it. He hasn't eaten since he lost it, though, so we'll have to see how that goes.
