Brain is the most important part of the body; it grows very rapidly from 6th week of gestation period. Maternal nutrition has an effect on embryo and placenta. Since 1995 there has been no change in under 3 children nutrition and wasting has gone up by 3%. Breastfeeding should go on till 2 years and it is the perfect nutrition source. There are various phases in which a baby matures while taking in human milk during the first two years of life. Child receives everything through breastfeeding except Vitamin K, D and B12. Vitamin D can be obtained by sunlight since sun is the major source. Vitamin B12 can be less in the infants whose mothers are vegetarian. If there is faltering in complementary feeding then nature takes its course and uses fat. A human infant doubles in weight by 5 to 6 months. For low birth babies it is recommended that cattle milk is not used and a vegetarian life is adopted. Home prepared food is recommended and infection in home should be taken care of. Egg white, broccoli, ice-cream, chocolate are not advised for under one infant. Vitamins are important, though they do not provide any energy yet they are important. Vitamins act as catalyst in metabolization of minerals. While a human body can create few vitamins, it cannot create a single mineral. Lymphocytes proliferation is done by vitamin B6 and stops if Selenium is low.
