Today DD who is almost 4 said: 'do you want me to show my private parts?' DH and I probably looked a bit shocked (as totally unexpected), so she thought she did something bad. When asked who told her this she named a boy at her nursery. I know the boy, he is sen and almost doesn't talk, so I don't think it was him.
What would you do? DH does not seem to be bothered, but I am certain we need to do something (eg speak with the nursery, DD about it...)
