Babies who cry constantly are often termed as colic, although there seem to exist a number of explanations regarding what is colic. A recent study had linked babies with colic to mothers who suffer from severe post partum depression and stress from handling a baby without any support system.
Post partum depression is the depression that several mothers suffer after childbirth. When mothers suffering from such a depression also go through difficulty in handling infant tantrums, parenting responsibilities, lower self esteem and a dysfunctional family, the result can be very detrimental for both the newborn and the mother.
The researchers have termed colic as the parental threshold for infant crying spells. Mothers who come from dysfunctional families with poor communications, role confusions, poor handling of emotions, and lack of interaction between the family members are often unable to cope with the scene and maternal responsibilities.
Newborns brought up in such a family may have difficulty in establishing fulfilling social relationships.
