Pan gafodd yr ymrwymiadau hyn eu pennu, roedd y cyngor gwyddonol yn glir. Roedd angen inni leihau nifer y cyfleoedd i ryngweithio rhwng pobl er mwyn rheoli trosglwyddiad y feirws a lleihau lefelau heintio. O ystyried hynny, roedd angen gofalu am blant yn y cartref, os oedd hynny’n bosibl, ac roedd angen sicrhau bod nifer y plant mewn ysgolion a lleoliadau gofal plant yn isel. Gofynnwyd i leoliadau gofal plant flaenoriaethu gofal plant i weithwyr hanfodol ac i blant agored i niwed.
At the time these commitments were made, the scientific advice was clear. We needed to reduce the number of interactions between people to both manage transmission of the virus and reduce infection levels. Wherever possible children were to be cared for at home, and the numbers of children in schools and childcare settings were to remain low. Childcare settings were asked to prioritise the care of the children of critical worker and vulnerable children.
