Education Minister Leighton Andrews has announced £4m extra funding over two years for Welsh-language training for early years teachers.
The package is to support the Welsh Assembly Government's Foundation Phase which promotes a play and involvement way of learning.
It is set to help around 330 people a year in Welsh and bilingual practice.
Mr Andrews said: "The demand for Welsh-medium practitioners is growing as the Foundation Phase rolls out."
A Welsh Assembly Government spokesperson said: "The money will be spent on training early year's practitioners in Wales such as classroom assistants and support workers.
"It's designed to help those who might already speak Welsh develop the confidence to use it in the classroom and those unable to speak language develop a new skill through work-based learning.
"Funding is for courses so as the demand for Welsh in the Foundation Phase grows we have qualified practitioners available."
Training will be delivered through two learning schemes which come under the remit of Trinity University College in Carmarthen.
The funding is in addition to £6m already available in Welsh-language training for the early years sector since 2008.
Mr Andrews added: "The £4m over the next two years will make a big difference in delivering the training that we know is necessary."
