I read this poem back in the sixties. It is a very sad poem about a little child who will not do something her mother wants her to do and the mother puts her to bed early in a "sunny cot". But she will not kiss the child goodnight.
It is a tormented poem written from the mother's point of view about repeated attempts of the child to ask the mother for a kiss, because she cannot sleep feeling she is alienated from her mother. In the end, the mother relents but it is too late. The child is dead.
The verse goes something like "Angels hovered overhead, in my arms my child lay dead."
It then goes on to warn other parents not to do likewise.
I think it has about 12 -16 four-line verses.
Does anyone know this poem or anything about it?
