Love, care and concern are the three common emotions found in every parent. In nature, the sweetness of relationships between parents and child is not restricted in the human world only, it is eternal and present in the animal world too. The mother-infant relationship in non-human primates is longer-lasting and more intense than it is in most other mammals. One reason for this is that the physical association between primate mothers and infants is very close. Infants cling to their mothers’ bodies almost constantly for at least the first few months of life. The mother provides the infant with food, warmth, transportation and protection. Compared to other mammals of similar size, primates have a long period of immaturity. They have relatively few innate behaviour patterns and must learn to cope successfully with the physical and social world. This learning occurs in the protected setting of a social group and is mediated by the mother-infant relationship.
