Emmie, I knew someone who had a baby in 1942 and was forced to hand him over into child care. As far as I know, she never saw him again but I would say she was one of those who you describe in your post at 08.29.
On wider note, I don't think the state had much consideration for the welfare of children back in those times, even though they will say they did. You only have to look at the Lost Children of The Empire, or Oranges and Sunshine, to get some idea.
Tony Blair did apologise, in 1999 I believe, for the issues raised in Oranges and Sunshine, but the Child Migrants' Trust is still, to this day, trying to re-unite families.
