When is the best age for solid food to be introduced into the infant's diet?
a. 2 to 3 months c. When birth weight has tripled
b. 4 to 6 months d. When tooth eruption has started
ANS: B
Physiologically and developmentally, the 4- to 6-month-old is in a transition period. The extrusion reflex has disappeared, and swallowing is a more coordinated process. In addition, the gastrointestinal tract has matured sufficiently to handle more complex nutrients and is less sensitive to potentially allergenic food. Infants of this age will try to help during feeding. Two to 3 months is too young. The extrusion reflex is strong, and the infant will push food out with the tongue. No research base indicates that the addition of solid food to bottle-feeding has any benefit. Tooth eruption can facilitate biting and chewing; most infant foods do not require this ability.
