As part of her campaign, Badavi has been visiting nurseries and schools to read to the children from her book The Big Sunny Adventure.
She also sings and dances with the youngsters to a song which has actions showing how to apply sun cream.
Badavi said children remembered stories and, once they understood the message, they began reminding their parents about sun cream and sun safety.
Schools visited by Badavi have included the Maynard School in Exeter.
Pupils said they understood the message after the nurse’s assembly.
Seven-year-old Nati said she learnt that “if you don’t put sun cream on, you’ll get sunburnt, and that isn’t good because it really hurts.”
Portia, also seven, remembered that “dogs needs some special sun cream as well and you have to put it on their nose.”
“You need a lot of sun cream” added six-year-old Tilly “and you need to make sure you’ve rubbed it in properly”.
Katie Greenwood, head teacher of pre-prep at the school, said Badavi’s use of storytelling and song was “a really good way to engage young children”.
She added: “I’m sure that they’re going to go home and talk to all of their families about everything they’ve learnt today.”
“I’m [also] sure there’ll be dogs getting sun cream on their noses.”
