Growth and development, nutrition, assessment & PREP U
infant milestones
*0-28 days= eye blink *1-4 months= attends to noises *4-8 months=recognizes words *8-12 months= enjoys rhymes and songs
Infant feeding
-Breast milk is nutritionally superior -Cognitive benefits associated with breastfeeding -Many U.S. infants are exclusively or predominantly formula fed -Formula feeding results in negative outcomes in underdeveloped countries "Milk will not fully provide the child's needs for iron, which is found in solid foods."
Erikson Developmental Theory
-Infancy- 1 yr.: Trust vs. mistrust 1-3 yrs.: Autonomy vs. shame and doubt 3-6 yrs.: Initiative vs. guilt 6-puberty: Competence vs. inferiority Teen years-into 20's: Identity vs. role confusion 20's-early 40's: Intimacy vs. isolation 40's-60's: Generativity vs. stagnation 60's-up: Integrity vs. despair

Rooting reflex disappears
4 months Movement of the tongue, mouth and/or head toward the stimulus a baby's tendency, when touched on the cheek, to turn toward the touch, open the mouth, and search for the nipple
Moro reflex disappears
4 months (Moro reflex is symmetric abduction and extension of the arms followed by adduction of the arms, sometimes with a cry)
Moro reflex disappears
4 months (Moro reflex is symmetric abduction and extension of the arms followed by adduction of the arms, sometimes with a cry) Reflex in which a newborn strectches out the arms and legs and cries in response to a loud noise or an abrupt change in the environment Infant reflex where a baby will startle in response to a loud sound or sudden movement.
The step reflex disappears by age?
6 weeks This reflex is also called the walking or dance reflex because a baby appears to take steps or dance when held upright with his or her feet touching a solid surface.
birth weight doubles by, triples by
6mo, 1y
anterior fontanelle closes by...posterior by..
AF -18 months, PF - 6-8 weeks
Infant weight gain
Birth weight doubles by 4 to 6 months Birth weight triples by 1 year
Breastmilk composition

vaccine schedule
DTaP, Hib, pneumococcal, meningococcal by 6m Start influenza and 6m MMR at 1y and 5y HBV and HPV at 12y
Hearing development
Fetuses (26-28 weeks) are sensitive to sound Babies show recognition of sounds they heard in utero repeatedly after they are born By 18 months, babies can detect the direction of a sound Noises must be 10 to 20 decibels louder for babies to hear it Children are 13 before they develop an adult-level of sound sensitivity
teeth development
First teeth usually erupt 6-8 months lower central incisors usually first Some infants fussy during teething from swollen, inflamed gums Cold teething ring may alleviate some discomfort begins b/w 6m and 2 1/2 yrs age in months - 6 = # of teeth 20 deciduous(baby teeth) lost by 6-12 yrs
Vaccinations at a six-month well-child visit.
HBV, DTaP, Hib, IPV, PCV
Newborn vital signs
HR 100-160 R 40-60 BP 60-80 systolic; 40-50 diastolic respirations of 1 mo old infant are irregular and periodically pause
Newborn vaccine
Hep B- HBsAg recombinant
Infant Nutrition
Nutrition a. The infant may breast-feed or bottle-feed (with iron-fortified formula), depending on the mother's choice; however, human milk is the preferred form of nutrition for all infants, especially during the first 6 months. 6 b. All infants should receive daily vitamin D supplementation (200 IU) starting in the first 2 months of life to prevent rickets and vitamin D deficiency. c. Iron stores from birth are depleted by 4 months of age; if the infant is being only breast-fed, iron supplementation usually with iron-fortified cereal is needed. d. Whole milk, low-fat milk, skim milk, other animal milk, or imitation milk should not be given to infants as a primary source of nutrition because these food sources lack the necessary components needed for growth and have limited digestibility. e. Fluoride supplementation may be needed at about 6 months of age, depending on the infant's intake of fluoridated tap water. f. Solid foods (strained, pureed, or finely mashed) are introduced at about 5 to 6 months of age; introduce solid foods one at a time, usually at intervals of 4 to 5 days, to identify food allergens. g. Sequence of the introduction of solid foods varies depending on physician's preference and usually is as follows: iron-fortified rice cereal, fruits, vegetables, then meats. h. At 12 months of age, eggs can be given (introduce egg whites in small quantities to detect an allergy); cheese may be used as a substitute for meat. i. Avoid solid foods that place the infant at risk for choking, such as nuts, foods with seeds, raisins, popcorn, grapes, and hot dog pieces. j. Avoid microwaving baby bottles and baby food. k. Never mix food or medications with formula. l. Avoid adding honey to formula, water, or other fluid to prevent botulism. m. Offer fruit juice from a cup (12 to 13 months or at a prescribed age) rather than a bottle to prevent nursing (bottle-mouth) caries; fruit juice is limited because of its high sugar content.
infant weight
Should double weight by 6 months and triple it by 1 year old.
