One factor that is big in this whole issue of childcare is put forward very well by James and Joyce Robertson, reviewing the work of their entire life in their 1989 book "Separation and the Very Young". They both worked at the Tavistock Clinic in England and did some filming of very young kids when they were separated from parents when put in hospital. Their film "A Two-Year Old goes to Hospital" literally changed the practise of not letting parents visit young children in hospital -- world wide.
They then did a series of equally powerful and significant films, the most famous of which is JOHN, a brief description of which follows in the next article - The Problem of Professional Anxiety. At age 17 months John is a healthy baby and is put in residential nursery care for 9 days. Just 9 days. A normal kid. He is put in this place. It isn’t daycare, it's around the clock day care in Britain twenty years ago. Well run, caring staff. It's a black and white film with voice over sound. James told me the original soundtrack would have made the film totally unbearable. It will scare the hell out of you, or make you mad. All James Robertson did was go to the nursery every day with his movie camera and record what happened to John emotionally while his mother was in hospital having a second baby and father visited periodically.
What the point is in this piece, and it is lifted out of their most recent book, is the final line which you’ll see in bold at the end of that article, "I could kill you", said a distinguished psychoanalyst after seeing the film. So those of us who are psychiatrists and experts really can be resistant to looking at the damage inflicted on children. If you’ve ever said anything about the dangers of daycare publicly you'll know. Ask Burton White.
