While there is increasing concern about developing and reinforcing children’s physical and emotional security, researchers have been busy working out the actual mechanics, even at the cellular level, of how this can be achieved.

This report represents what we have learned and we hope that it will contribute in a small way to the making of the brave new ‘post-Covid’ world
