Families in Wales are being "punished" by childcare bills for under-twos that are more than double the average of those in England, Oxfam Cymru has said.
Parents in Wales with children who are under two do not receive any government help with childcare costs, whereas in England parents can claim 15 hours of free childcare a week for children aged between nine months and two years.
Children's charity Coram said nursery costs for under-twos were now more expensive in Wales than anywhere else in Great Britain.
The Welsh government said it had invested more than £100m a year to sustain and grow high quality childcare.
