Judy Holtzer Knopf mentioned the UK usage of the term 'weaning'. The correct term I belive for cessation of bf is 'sevrage' but I have never heard anyone use it. Nowadays we tend to use 'weaning' to mean introduction of solids as well as ceasing bf, but I don't know which term would have been used 70 years ago. I too remember the study, which resulted when old records were found. It certainly was flawed because it was not corrected for factors such as poverty, and typically the poorest would have bf the longest and would have had a much more unhealthy diet generally. I don't know if they looked for more positive long term effects of bf. -- Linda Cairns Tilehurst, Berkshire, UK - Mum to Jonathan (9), Stephen (7), and Nicky (6) National Childbirth Trust Breastfeeding Counsellor and Volunteer Egnell Breastpump hire agent Snail: 6 The Cedars, Tilehurst, Reading, RG31 6JW, England
