Last reviewed 11/2020

Breastfeeding results in improved maternal and infant outcome in developed as well as in developing countries
Benefits of breast feeding in children  

  • human breast milk provides protection against infection and contains secretory IgA, WBC, whey proteins (lysozyme and lactoferrin) (1)
  • the protein content of human breast milk is less likely to induce allergic reactions and the infant may be less at risk from sudden unexplained death
  • in general breastfeeding results in an reduced risk of:
    • gastrointestinal tract infection
      • a 64% reduction in the incidence of nonspecific gastrointestinal tract infections is seen associated with any breastfeeding
      • this effect lasts for 2 months after cessation of breastfeeding
    • respiratory tract infections
      • in exclusive breastfeeding for 4 months or more
        • 72% reduction of risk for hospitalization for lower respiratory tract infections in the first year 
        • 74% reduction in severity of respiratory syncytial virus bronchiolitis when compared to infants who never or only partially breastfed
      • exclusively breastfed for >6 months – a fourfold reduction in the risk of pneumonia when compared to infants who were exclusively breastfed for 4 to 6 months
    • otitis media (OM)
      • any breastfeeding (compared with exclusive infant formula feeding) will decrease OM by 23%
      • exclusive breastfeeding for > 3 months will reduce the risk by 50%
      • exclusive breastfeeding for 6 months results in an 63% reduction in serious colds and ear and throat infections
    • necrotizing  enterocolitis (NEC)
      • a 77% reduction in NEC in preterm infants fed an exclusive uman milk diet compared with those fed human milk supplemented with cow milk-based infant formula products
    • sudden infant death syndrome (SIDS)
    • allergic diseases
      • exclusive breastfeeding for 3 to 4 months – reduced incidence of clinical asthma, atopic dermatitis, and eczema by 27%  in a low-risk population and up to 42% in infants with positive family history
    • celiac disease
      • reduction of 52% in the risk of developing celiac disease in infants who were breastfed at the time of gluten exposure 
    • inflammatory bowel disease (IBD)
      • associated with a 31% reduction in the risk of childhood IBD
    • obesity
      • 15% to 30% reduction in adolescent and adult obesity rates if any breastfeeding occurred in infancy compared with no breastfeeding.
    • diabetes
      • exclusive breastfeeding for at least 3 months – 30% reduction in the incidence of type 1 diabetes mellitus and a 40% reduction in type 2 diabetes mellitus
    • childhood leukaemias and lymphomas
      • A reduction of 20% in the risk of acute lymphocytic leukemia and 15% in the risk of acute myeloid leukemia in infants breastfed for 6 months or longer
  • positive effects of breastfeeding on long term neurodevelopment has been observed in preterm infants       
  • convenience especially with hygiene, which accounts for important improvements in the amount of diarrhoeal illness over bottle fed infants (2)
  • breast milk is easily digestible and always at the correct temperature
  • possible errors in the formulation or preparation of the artificial milk are eliminated

Benefits of breastfeeding for the mother include:

  • the process of breast feeding helps contract the uterus and accelerate involution thereby decreasing the risk of post partum haemorrhage
  • pre-menopausal breast cancer and ovarian cancer are less common in women who have borne children and breast fed them
  • breast feeding is a process that gives satisfaction to the mother and child
  • breast feeding has a contraceptive effect which helps in child spacing. This is due to high prolactin levels
  • accelerated weight loss and return to pre pregnancy body weight
  • economic benefits (2)

For these reasons, breast feeding is always encouraged unless there are strong contraindications.
