Young children have started to receive universal free school meals this week, but older children in Wales must wait.
Reception pupils, aged four and five, are being offered the meals from this month as part of a phased rollout to all primary school children by 2024.
Eight local authorities have said year 1 and 2 pupils will also qualify from the start of term.
But the Welsh Conservatives said the plans were "wrong" to include the children of "millionaire families".
All of Wales' approximately 272,000 primary school pupils are set to get free lunches by 2024. It is part of a deal between Plaid Cymru and the Labour Welsh government.
