An extra 3,000 free childcare places will be created for two-year-olds from April, the Welsh government has said.
The money for these extra places in the Flying Start programme will be funded as part of £100m pledged by the Welsh government to improve availability.
It is not yet known which areas will benefit, and eligible families will be contacted in the new year.
The Welsh Conservatives said more affluent families would benefit "while the most deprived lose out".
Of the remaining cash, £70m will pay to upgrade childcare settings and £3.8m will be spent on boosting Welsh language provision.
