Confusion over a free childcare scheme has led to some parents receiving unexpected bills, a report has found.
Working parents of three and four-year-olds in Wales are entitled to 30 hours of free childcare a week for up to 48 weeks of the year.
Researchers found some parents were using up their entitlement early and receiving unexpected bills for some school holiday childcare.
The Welsh Government said the free childcare offer was helping families.
First introduced in pilot areas in 2017, the Welsh Government's flagship policy entitles working parents to 20 hours free childcare on top of the existing 10 hours of early education provision.
