I must be weird because I was excited when my kids started losing their teeth. My oldest lost her first one a couple months after turning 6. She is 8 1/2 now and at the moment has 2 missing teeth (she's lost 8 in total, I think).
My son lost his first tooth (actually he pulled it out because the adult tooth was coming in behind it) just before he turned 6. He has 2 missing teeth right now (he's 7).
My middle daughter lost her first tooth last summer at 5 1/2. She was so surprised. She has 2 missing teeth right now (she's 6 now), too, with 2 more that are wiggly. Which I thought was funny because she was a late teether. I mean really late. Her first tooth came in a few days after she turned ONE! Yet she lost her first tooth earlier then her siblings.
The week she lost her first tooth the other two lost teeth, too. We had 6 teeth fall out in like a week and half. The tooth fairy was super busy...and broke that month, lol.
