DD told other children there is no tooth fairy -- moms mad
A parent called me tonight to tell that on a Girl Scout fieldtrip my DD (almost age 7) told the other girls in the car that there is "no such thing as the tooth fairy, it's our parents." Apparently the driver (another mom) was very upset. The mother that called (not the driver) even said, "I don't know what I would have done if she had said it in front of my daughter." Apparently the driver made something up about it and then changed the subject.
I do know that my daughter is very skeptical of a fairy flying into her room during the night but I would never admit to her that it was made up (mostly because I thought she'd then start to doubt Santa Claus). I told the mother that called that I would talk to my daughter about it.
I did feel bad but I am slightly taken aback that these mothers don't expect that these things may start to happen at this age. I did tell my daughter to keep her opinions to herself on the subject but she didn't do it maliciously.
Did I under-react to the situation?
