Learning Objectives:  Chapter 8 - Infancy Define key words o Full term infant, failure to thrive, rooting reflex, suckling reflex, motor development, hydrolyzed  protein, food allergy, food intolerance Full term infant : born 37-42weeks (typically40weeks); weighs 5.5-8.5 pounds; 18.5-21.5inches long          Failure to thrive : inadequate weight or height gaindue to inadequate Calorie intake          Rooting reflex : when one cheek is touched,infant turns his/her head toward that cheek and opens mouth          Suckling reflex : tongue movement (reflex) forfeeding         Motordevelopment:          Hydrolyzed protein : enzymatically digested protein,or single amino acids (proteins already broken down)  not found in foodsnaturally          Food allergy : abnormal immunological responseto a specified food           Food intolerance : adverse reaction to foods bydigestive system and metabolism Recognize a healthy birth weight, a low birth weight  (small for gestational age / preterm) and a high  birth weight (large for gestational weight  / macrosomia) A healthy birth weight is 5.5 to 8.5 lbs with a range of 37 to 42 weeks gestation. A low birth weight is less than 5.5 lbs. High birth weight is more than 8.5 lbs, or greater than 90 percentile Define Adequate Intake (Dietary Reference Intakes) for infants. Infants don’t have a dietary reference intake, they have adequate intake that are  followed because each child  is different and have different needs       Average nutrients for thriving/healthy babies        Higher in  All vitamins associated with growth Vitamin D – 10x adults – needed for bone  growth Vitamin C – 5x adults – needed for bone growth Vitamin A –  Iodine– 7x adults         Needs are higher during 0-6months compared to 6-12months  Energy (100kCal/kg) adult’s 40kCal/kg Protein (2.0g/kg)  - adults need 0.5g/kg Fat (50% of total Kcal) – adults <35% Describe methods used to physically assess growth in infants. Some of the methods used to assess growth are measuring birth weight, length, and head circumference for  gestational age Recognize a normal pattern of growth for an infant (height / weight) over a 12- month period as plotted on a  weight / age and height / age growth chart.

On the chart, a child weight (measured on bottom) and length (measured on top) follows a curve. If the child’s  growth pattern falls under the curve, the child is at  risk and needs to be watched. No child, even those in the  95% should evergo  under his/her curve.
