Wales’ education minister has appealed to those classed as “key workers” entitled to childcare to “think very carefully” before sending their children to school.
Schools are closed, but some will look after children of parents who qualify in a broad list of professions.
Kirsty Williams said people should ask if their role can be done at home, before they take up an “emergency service”.
Children should only be sent into school if there is “no other alternative”, she told a press conference.
Ms Williams said: “If you have a partner who is not a key worker, what arrangements can you put in place for your family, for your children to be cared at home?
“Children are best kept at home at this time.
“We need to keep the numbers [at school] as low as possible, and parents should do all that they can to care for their children at home and only use these facilities as a last resort,” she added
