Maternal Deprivation Theory, Bowlby.

The Maternal Deprivation Theory was developed by John Bowlby (1951) and focuses on how the effects of early experiences may interfere with the usual process of attachment formation. Bowlby proposed that separation from the mother or mother-substitute has a serious effect on psychological development. Bowlby famously said that ‘mother-infant love in infancy and childhood is more important for mental health as are vitamins and proteins for physical health.’ Being separated from a mother in early childhood can have serious consequences according to Bowlby.
