Though death in infancy was common, almost half-expected in the past, the psychological effects of the loss of a child on the parents could be devastating and long-lasting.
My Oh's grandmother lost her second son, aged 14 months in 1915. She already had one son and had another in 1918 ( when her husband came back from the war).
The younger lad was my Oh's father. He spent his entire life in the shadow of the dead brother, constantly berated and belittled by his mother, she said he was never as good as the lost baby would have been.
The psychological complexity of the family must have been such that noone ever took her to task about her unreasonable behaviour.
A sad story in so many ways.
