Document Summary

Growth and change in years 2 & 3. Physical growth slows down from its pace of first year. Remains more rapid then it will be later in life. During toddlerhood, children lose baby fat and become leaner and longer. Head is 1/5 of 2nd year olds height. Toddlers in developing countries do not grow as rapidly (once they start eating solid food, they receive less protein because don"t have as much food in developing countires) Protein deficiency limits growth and more vulnerable to disease. Kwashiorkor: protein deficiency in childhood, leading to symptoms such as lethargy, irritability, thinning hair, swollen body, which may be fatal if not treated. Micronutrients: dietary ingredients essential to optimal physical growth, including iodine, iron, zinc and vitamins a,b,c,d. Steep increase in synaptic density is what distinguishes early brain development. Synaptic density: density of synapses among neurons in the brain, peaks. After peak of synaptic density, synaptic pruning begins around age 3.
