Os caiff y Bil ei basio gan Gynulliad Cenedlaethol Cymru, ni fydd rhieni ac oedolion eraill sy'n gweithredu fel rhieni yn gallu cosbi plant yn gorfforol mwyach - bydd gan blant yr un amddiffyniad rhag cosb gorfforol ag oedolion.
If the Bill is passed by the National Assembly for Wales, parents and other adults acting in a parental capacity will no longer be able to physically punish children – children will have the same protection from physical punishment as adults.
