Would Kant say that you can't tell your kids about the tooth fairy because it's a lie?

Or would he say that it's okay because we could rationally will that every parents tell their kids that there is a tooth fairy without contradiction? And also in this case the child is not being used as a means, but rather the child's enjoyment is the end in itself?

He would say it's still immoral because your still disrespecting the autonomy of the child by willingly stating a falsehood. This question is very similar to the "can a parent lie to their terminally ill child that theyll be okay" and deontologists have already stated that they cant on that one either (but you can choose not to answer them or dodge the question just fyi)
