This actually just happened last night with my son’s third tooth. He sat bolt upright and then slumped over backwards as I stood there with my hands behind my back. I was holding the little tin with the tooth in it already.
He didn’t remember a thing this morning, I think he wasn’t actually awake.
Give her a bottle of NyQuil unsupervised and bash her over the head with a brick for good measure.
The tooth fairy is one of those ones that even if your kid learns the truth, nobody is going to get too upset. You can just keep giving them the money yourself, and tell them not to tell their friends, because if they tell their friends, their friends who have stingy parents will stop getting money.
Also, some kids are scared of the tooth fairy.
The trick my mom told me she’s did was she’s swapped it out the moment she tucked me in. But she was also smart to put it in the pillow not under it as she said the tooth could fall down and I wouldn’t get any money.
We put the tooth in a glass of water rather than under the pillow. Much easier.
