The article is related to Annaprasan as per the Vedas (Sacred Texts) of ancient India [15]. This activity is technically called Infant & Young Child Feeding (IYCF) in public health & Complementary Feeding (CF) in terms of the science of nutrition [2-4]. The 0-1 year age group is called technically an Infant. The 1-2 year age group is called as Young Child (YC) [2]. All these interventions are critical as these interventions reduce mortality. Further, it not only reduces mortality but is also cost effective. When we breakdown the stage of infant, the first stage of IYCF is from 6-8 months age group as the IYCF should be introduced to the child latest by the age of 8 months. It is called Complementary Feeding (CF) as it completes the nutritional needs of the infant & young child along with breast feeding [2-23]. The second stage is from 9 months to 24 months where along with breast feeding, the frequency & diversity of the complementary foods is critical [4]. In all, the article deals with 527 days or the period from 6 months of age to 2years of age. Here the feeding includes Breast Feeding (BF) from 6 months of age onwards along with Semi Solid Foods (SSF) to 24 months of age [2-4]. The article discusses the history & evaluation of the IYCF concept, its current situation, challenges & priorities related to IYCF. Finally, it sees the role of IYCF in this stage & how the effective roll out of the concept through the public health system can optimize the benefit to the child. This is the base of the nation’s future & the 527 days of independent life is a critical stage to set the stage for nutrition for an entire life span of at least 7 decades. Addressing these issues through effective IYCF rollout will reduce under nutrition & over nutrition in the later years of the child [2-16].
