Research by the Children's Mutual, which provides financial services for children, found that teaching was the most popular ambition among the 1,000 children surveyed in the UK.
Medicine dropped to second place, and becoming a vet was third.More children still want to be doctors than police officers, footballers or firefighters. Becoming a TV or cartoon character languishes in ninth place.
The Children's Mutual warned that their children's ambitions would mean many parents found themselves faced with bills of up to £130,000 in 12 years' time, to cover tuition fees and other expenses.
'It's encouraging that today's five- and six-year-olds have such lofty ambitions,' said Tony Anderson, the company's marketing director.
'The top three career choices all require higher education and training to fulfil them, meaning parents are likely to have to find lump sums to help their children achieve their aspirations.'
