Mae'r Ddeddf yn canolbwyntio ar alluogi pawb, gan gynnwys plant a phobl ifanc, i sicrhau eu llais eu hunain mewn penderfyniadau amdanynt hwy ac i'w galluogi i fyw'n ddiogel gyda'u teuluoedd a bod yn aelodau egnïol a chyfranogol o'u cymunedau: mae hyn yn hanfodol i sicrhau llesiant.
The focus of the Act is on enabling all people, including children and young people, to secure their own voice in decisions about them, to enable them to live safely with their families and to be active and participating members of their communities: this is critical to securing wellbeing.
