O heddiw ymlaen, bydd y pedwar plentyn yn gallu gweld eu hwynebau ar sgriniau mewn sinemâu ac ar y teledu a chlywed eu lleisiau ar y radio, wrth iddyn nhw helpu Llywodraeth Cymru i lansio ymgyrch i hyrwyddo Cynnig Gofal Plant Cymru.
From today, the four children will be able to spot their faces on cinema and television screens and hear their voices on the radio, as they help the Welsh Government to launch a campaign to promote the Childcare Offer for Wales.
