The government is providing more support for early years education through an extension of the pupil premium.
Schools, nurseries and childminders are to be given up to £300 for every three and four-year-old from a low-income family to ensure they do not fall behind at an early age.
Totalling £50 million, the funding is designed to narrow the attainment gap between young children from such families and their better-off peers.
Some seven areas are to receive a share of a £1 million pot to trial the new support in advance of its introduction nationwide next April.
Deputy prime minister Nick Clegg said: "I'm so proud that we've been able to deliver this early years pupil premium so that toddlers from the poorest families get the support they need, which will pay dividends later in life."
Nurseries are to be given discretion over how to spend the money, which could be used to recruit more specialists in certain activities such as speech and language, for example.
