Daeth adolygiadau ymarfer plant newydd i rym ar 1 Ionawr yng Nghymru. Mae'r broses newydd hon yn deillio o adroddiad Arolygiaeth Gofal a Gwasanaethau Cymdeithasol Cymru a gyhoeddwyd ym mis Hydref 2009 – Gwella Ymarfer ar gyfer Amddiffyn Plant yng Nghymru – a ddaeth i'r casgliad bod adolygiadau achosion difrifol bellach yn aneffeithiol o ran gwella ymarfer a chydweithredu rhwng asiantaethau. Bydd adolygiadau ymarfer plant newydd yn parhau i gael eu cynnal o dan yr un amgylchiadau lle mae plentyn yn marw neu'n cael anaf difrifol, a lle mae cam-drin neu esgeuluso yn hysbys neu'n cael ei amau. Bydd yn arf dysgu effeithiol ar gyfer partneriaid diogelu.
New child practice reviews came into effect on 1 January in Wales. This new process stems from the Care and Social Services Inspectorate Wales report published in October 2009 - Improving Practice to Protect Children in Wales – which concluded that serious case reviews had become ineffective in improving practice and inter-agency cooperation. New child practice reviews will continue to be undertaken in the same circumstances where a child dies or is seriously injured and abuse or neglect is known or suspected and will be an effective learning tool for safeguarding partners.
