• Prof Helen Ball: Rethinking how we do sleep: the view from evolutionary medicine.

In the recent historical past something interesting has happened to how we think about and do sleep. In the quest for 'a good night' we sleep in private sanctuaries, alone or in pairs, on special surfaces, in total darkness and silence. But this is not how sleep evolved, nor how most humans sleep. Evolutionary medicine suggests that many 21^st century 'sleep problems' result from a mismatch between our cultural expectations and our evolved biology. Do we need to redefine what we expect from 'a good night's sleep'?

• Prof Helen Ball: Keynote speaker, Breastfeeding and infant sleep: a research update

Negotiating the relationship between infant feeding and sleeping has become a minefield for new parents with claims and counter-claims about how, where, when and with whom infants should or should not sleep.  New research articles appear weekly supporting apparently contradictory positions, while many studies regarding infant sleep fail to take the particular needs of breastfeeding mothers and infants into account.  This talk summarises the latest findings regarding sleep training, scheduling, sleep-sharing and SIDS-investigations, including the latest results of Professor Ball's most recent projects (the NECOT trial and the Bradford Infant Care Study (BradICS)) regarding breastfeeding, bed-sharing and other infant sleep environments.

Biology, Infancy & Mothering Conference, Calman Learning Centre, Durham University, Durham, UK.

A one day conference for Researchers and Health Professionals interested in mother-infant behaviour and biology was held in Durham at the Calman Learning Centre, Durham University, on Jan 7th 2010. Organised by Professor Helen Ball and her research team the conference featured keynote talks from Dr Nils Bergmann, Professor Wenda Trevathan, Professor Helen Ball and Dr Suzanne Colson and presentations from Sleep Lab doctoral students Kristin Klingaman and Lane Volpe. Presentations focussed on new research and its implications for practice. Handouts from each of the talks can be downloaded from the 'Presentations' page of this website. Sadly, due to weather, Dr Kerstin Uvnas-Moberg experienced travel difficulties and was unable to attend.
