INFANT NUTRITION
BREAST MILK › Best food for the infant during the first 12 months/2 years › The only food necessary for the first 6 months 30ml: capacity of a newborn’s stomach 240ml: by 1 yr Normal full-term infants can thrive on an iron-fortified formula or breast milk without the addition of solid food for the first 6 months
HIGHLIGHTS
0-3 › ›
› › › › ›
4–6 ›
› ›
Feeding only breast milk or formula for first year Always hold infant when feeding, do not prop bottle when feeding Limit water intake to 0.5 oz to 1 oz at a time Avoid use of honey or corn syrup Allow non nutritive sucking 2 – 3: amylase present in saliva 3 months: biting movement is present Introduce solid food without added salt or sugar, iron-fortified cereal, one food at a time Avoid use of juice or sweetened drinks Feeding from spoon only
7–9 Introduce finger foods and cup when infant is able to sit up › Have infant join family members at mealtime › Allow self feeding › Offer fluids after solids › Introduce diluted juice in a cup › Avoid sugary desserts and soda › Chewing movement develops 10 – 12 › Offer 3 meals and healthy snacks › Begin weaning from the bottle and begin table foods › Avoid fruit drinks and flavored milk › Allow self feeding with spoon ›
Pre requisites in giving solid foods wanting to put things in his/her mouth able to suck small amounts of pureed food from a spoon interested in food eaten by others more frequent feeding can sit upright when supported with good control of the head and neck
Techniques for Feeding Solid Food › Offer new foods one at a time (1 week interval) Helps detect possible food allergy Helps to establish a sense of trust › Babies should be held in parent’s arms when introducing solid food for the first time

INFANT NUTRITION
Introduce solids slowly. All babies are different and progress at different paces. Start with single foods. Avoid nuts, whole peas, raw or undercooked undercooked pieces of fruit or vegetables (such as apple and carrot) as they can cause choking in babies. Always watch your baby when he/she is eating.
INSTITUTING SAFETY PREACAUTIONS
Aspiration prevention › Cylindrical objects are dangerous › Do not prop bottles when feeding › Clear small objects that could fit into an infant’s mouth › Safety with siblings Fall prevention › Don’t leave infants on an elevated surface surface unattended › Side rails should be raised Safety with siblings ›
Children under 5 years old are not responsible and knowledgeable knowledgeable enough about infants
Some preschoolers may be so jealous of a new baby that they may physically harm the infant if left alone Childproofing ›
› › › › ›
Check for possible sources of lead (plastic/rubber toys, wall paints, crib, etc) Infants are fascinated with holes Install safety gates on top and bottom of stairs Check bottom cupboards for safety Tables should be cleared of dangerous items Check play areas for small objects that could be swallowed
PARENTAL CONCERNS
Fostering Achievement of Developmental task ›
Trust VS Mistrust
Colic ›
Seborrhea ›
Paroxysmal abdominal pain that generally occurs in infants under 3 months of age
Cradle cap: scaly cap condition that results from infant head that is not washed frequently frequently
Miliaria ›
Prickly heat rash that occurs most often in warm weather, overdressed babies or those who sleep in overheated rooms.
SENSE OF TRUST
Meeting of infant's needs appropriately Consistency of care with active interaction › A synonym of trust is love Development is sequential; cyclical › Trust arises primarily from a sense of confidence that one knows what is coming next › Learning family traditions that will help them feel secure in the world as they will grow
BABY BOTTLE SYNDROME
No formula, fruit juice, or liquid with sugar during night time
do not put baby to bed with a bottle
give plain water only
The Toddler ( 1 – 3 years) • • • • • • • • •
Respiration and heart rate slows Speaks in two-word sentences Start of toilet training Baby fat disappearing Chest circumference greater than the head at 2 years Prominent Abdomen Noticeable lordosis Wide-based gait 20 deciduous teeth at 2 ½ years
Body Systems
Respirations slow slightly but remain abdominal HR slows, BP increases Less prone to lower respiratory infection Stomach capacity increases Less prone to gastrointestinal gastrointestinal infections Bowel and bladder control are possible IgG and IgM antibody production is mature; passive natural immunity effects are no longer effective

LANGUAGE DEVELOPMENT
Toddlerhood is a critical time for language development NO is a word frequently used by toddlers › A manifestation of their developing autonomy › To refuse or does not understand the task Exposure to conversation and reading Pronouns are difficult for this age Learn to speak language from imitating what they hear
PARALLEL PLAY play side by side or back to back paying little or no attention to each other Toys that require action like being together, and they may occasionally enjoy watching each other play, but, mostly, each is interested in what he is doing they don't understand sharing haven't learned it's not right to hit and shove and bite other people
PARENTAL CONCERNS
Toilet Training Prerequisites: › Sphincter control › Understands Understands the need and act of elimination › Desire for socially accepted action › Can walk › Ritualistic Behavior › Negativism › “No” to every question › The more parents try to make toddlers obey them, the more they resist › Make statements instead of questions › Offer choices › Discipline › Discipline: setting of rules › Punishment: consequence of breaking rules › General rules › Be consistent › Praise correct behavior than punish the wrong › Separation Anxiety
›
From 6 months to preschool years
Prolonged goodbyes lead to more crying › Sneaking out should be discouraged; fear of abandonment › Protest, despair, denial Temper Tantrums ›

Best approach: verbalize the disapproval of the tantrum and then ignore

Adult height reached by 15-16 years old
•
Fat deposits increase in hips, breasts, legs and arms

•
Heart and lungs enlarge dramatically
•
An increase in the number of red blood cells which carry oxygen from the lungs to the muscles-this does not occur in girls

Voice change occurs during the middle of puberty

Around 17-18 years of age physical changes are complete
Body Image •

•
Boys who mature earlier than their peers tend to have a positive self-image. self-image. To friends, relatives, and teachers they appear stronger and more mature than late maturing boys. They may be chosen for leadership roles and many excel athletically.
