If anyone is wondering about that book, I found this:
"In 1977, the BBC ran a series of 19 programmes (Other People?s Children) specifically designed to offer training to childminders. The series was accompanied by a booklet from the Health Education Council. The programme encouraged local childminders to network and this led to the formation
of the National Childminders Association (NCMA) with support from the BBC, the Equal Opportunities Commission and the van Leer Foundation. The NCMA membership was open to parents, local authority officials and childminders"
Wonder if anyone has the entire book scanned... probably not. Expect only the cover survives - though there may be a few copies laying around in some archives somewhere.
