Article 12 of the UNCRC states that children have the right to say what they think should happen when adults are making decisions that affect them and to have their opinions taken into account.
Mae Erthygl 12 o CCUHP yn nodi bod gan blant yr hawl i fynegi eu barn ynghylch yr hyn a ddylai ddigwydd pan fydd oedolion yn gwneud penderfyniadau sy’n effeithio arnynt, ac i’w barn gael ei hystyried.
