Some young people may need to be accommodated by the local authority up to their 21st birthday if they are being looked after in a community home which is suitable for children aged 16 and over.
Efallai y bydd angen i rai pobl ifanc gael llety gan yr awdurdod lleol hyd at eu pen-blwydd yn 21 oed os ydyn nhw'n derbyn gofal mewn cartref cymunedol sy'n addas ar gyfer plant 16 oed a hŷn.
