Nearly all general practices nationwide have signed up to a government scheme to provide free appointments and prescriptions for under 13s.
Health Minister Jonathan Coleman said 971 of the country's surgeries - or 96 percent - had joined the scheme, a take-up rate which had exceeded expectations.
Only 41 medical centres had not opted in to a government subsidy in exchange for proving free consultations, he said. All pharmacies had signed up.
District Health Boards will have to ensure children under 13 can get free after-hours care and prescription medicines in their area.
