Maternity blues
Maternity blues, also known as baby blues and postpartum blues, is a transient condition that 75-80% of mothers could experience shortly after childbirth with a wide variety of symptoms which generally involve mood lability, tearfulness, and some mild anxiety and depressive symptoms. Baby blues is not postpartum depression, unless it is abnormally severe.After the placenta is delivered, the placental "hormone factory" shuts down causing radical changes in hormone levels, and the woman can suffer symptoms due to withdrawal from the high pregnancy levels of estrogen, progesterone and endorphins. Combined with this shift in hormone levels is the physical, mental and emotional exhaustion - as well as sleep deprivation typical of parenting a newborn. All of these factors contribute to the condition.
Maternal deprivation
The term maternal deprivation is a scientific term summarising the early work of psychiatrist and psychoanalyst, John Bowlby on the effects of separating infants and young children from their mother (or mother substitute) although the effect of loss of the mother on the developing child had been considered earlier by Freud and other theorists. Bowlby's work on delinquent and affectionless children and the effects of hospital and institutional care led to his being commissioned to write the World Health Organization's report on the mental health of homeless children in post-war Europe whilst he was head of the Department for Children and Parents at the Tavistock Clinic in London after World War II. The result was the monograph "Maternal Care and Mental Health" published in 1951, which sets out the maternal deprivation hypothesis.
