Teddy's mum, Beth, says he started learning from educational programmes during lockdown.
A boy who taught himself to read as a toddler has been accepted as the UK's youngest member of Mensa.
Four-year-old Teddy, from Portishead in Somerset, can count to 100 in six non-native languages, including Mandarin.
His mother told the BBC's Radio Four Today programme that he taught himself to read when he was two years old.
