Re-elected in 2001, Davies was appointed NSPCC Parliamentary Ambassador in 2003 (−2005) following his proposed Regulation of Childcare Providers Bill in April 2003 which saw the law changed so that childminders were no longer permitted to smack children and parents had the right to see records of complaints about prospective childminders in respect of child safety. These provisions were subsequently adopted by the Government. He then proposed the Physical Punishment of Children (Prohibition) Bill in July 2003 which made striking children across the head, with implements or shaking them illegal. He sought to address children's issues with a Healthy Children Manifesto (June 2004) to ban junk food advertising to children and regulate food labeling (adopted by Government 11/06) and a School Meals and Nutrition Bill in January 2005 that sought to include nutrition in OFSTED and to ban unhealthy vending (provisions adopted 3/05 & 10/05). He also sponsored the Regulation of Hormone Disrupting Chemicals Bill (May 2004) to impose precautionary bans on chemicals with evidence of being dangerous. This bill was incorporated in the EU REACH directive 09/06 and supported by the World Wide Fund for Nature UK. He was also involved in a high-profile campaign for the release of British detainees being held at Guantanamo Bay.
