Article 15: Children have the right to meet with other children and to join groups and organisations, as long as this does not stop other people enjoying their rights.
Erthygl 15 yn dweud mae gan bob plentyn yr hawl i gyfarfod â phlant eraill ac ymaelodi â grwpiau a sefydliadau, ar yr amod nad yw hyn yn atal pobl eraill rhag mwynhau eu hawliau.
