Our daughter (3.5 years) has never tried to flush anything. Hopefully our son never tries! My friend, however, took her daughter to a department store (where they had those high-power toilets in the bathrooms) one day and her daughter managed to grab my friend's car keys and flush them! So, obviously they couldn't go home. Her sister had to come get her.
