National Breastfeeding Project in Thailand began in 1989. The main activities were the promotion of the Baby-Friendly Hospital Initiative; legislation on maternity leave; and the Code of Marketing of Breastmilk Substitutes and related products. The development of Baby – Friendly Hospital Initiative may in part explain the increasing of prevalence rate of breastfeeding. However, exclusive breastfeeding has not shown favorable increases. The survey in 2005 found exclusive breastfeeding at 6 months was 14.5% while the national target of the Ninth National Health Development Plan (NHDP) has been set at 30%. There are many factors affecting the success of breastfeeding promotion. The Ministry of Public Health, which is responsible for infant/child health, has to find solutions with the most potential for any problem related to such a matter, especially prevention of childhood diseases. Furthermore, it must also create an environment where good health fundamentals for physical and intellectual developments from infancy to childhood and maturity exist.
