I was so sorry for Ethan, and his mum. Having suffered from depression myself, I can totally identify with the selfish and inconsiderate aspects of the mother's behaviour. Fortunately for my ds, this was all prior to his birth, so I hope that he will never be affected in this way.
I am the product of a mother who suffered from depression when I was a baby, and times were so different then. There was no help, and depression was almost a dirty word, if it was diagnosed at all. It has certainly affected my life, and caused me many problems, which have been helped by counselling. Long story, but I suppose I am trying to say that at least Ethan stands a chance in life, as his mother will be able to get help for her depression, and the support is there if you ask for it.
I still felt like crying, seing him calling for his mummy, and trying desperately to reach the toy on the floor. I sometimes put my ds back in his cot, after his morning feed, if I can see that he is still tired, or if it is way too early to get up for breakfast. I bung a few toys in with him, and he plays himself to sleep, or just contentedly plays for an extra half hour. As soon as he starts moaning with boredom, or as soon as it is a decent hour to get up, I fetch him.
I too worry after watching this programme. Am I affecting his life by putting him back in his cot, and getting half an hour's more sleep? At the end of the day, he is stimulated well during the day, so I think that it is OK to teach him to be a bit self reliant. Just not for 3.5 hours!
