"B**bies" instead of blueberries and "c**k porn" instead of popcorn.
These are just two examples of the "adorable" ways children unwittingly mix up their words shared by parents on Mumsnet.
One mother told how her daughter's habit of calling blueberries "boobies" led to an embarrassing encounter in the supermarket, while a reception teacher had to compose herself in the stationary cupboard after a pupil informed her class that an octopus has eight "testicles".
Many parents said they continued to use their children's "adorable" alternative names long after their little ones learned to say the words correctly.
