UNIT 2 Flashcards
starts at the end of the first month up to the end of the first year of age. Infant’s growth and development during this period are rapid, and it is a time of continued adaptation.
The infancy period
It is the period which starts at the end of the first month up to the end of the first year of age. Infant’s growth and development during this period are rapid.
normal infant
is a helpful indicator of growth and development
Weight
The average birth weight of the infant is
2.5kg to 3.5kg (5.5lb to10 lb.)
They lose about ___day in the first 4-5 days after birth but regains weight by 10-12 days (30g per day).
20-30g per
Calculating the Infant`s Weight
Age in months + 9/ 2
Weight : the infant gains :
Birth to 4 months → ¾ kg /month 5 to 8 months → ½ kg / month 9 to 12 months → ¼ kg /month The infant will double his birth wt by 4-5 months and triple it by 1012 months of age
Infant’s length measured from the top of their head to the bottom of one of their heels. It’s the same as their height, but height is measured standing up, whereas length is measured while your baby is lying down.
Height
Height increase
1 inch / month during 1st 6 months ,
-7-12 months average HEIGHT
½ inch / month
Height increases __ at 1 year old
50%
Length increases about 3 cm /month during the
1st 3 months of age, *
increases 2 cm /month at age of
4-6 months,
7 – 12 months, it increases
1 ½ cm per month
The distance around the baby’s head, the infant’s head, is ¼ total body length. The average head circumference is about 34.5 cm at birth (13.5 inches).
Head circumference
It increases about 2 cm /month during the 1st 3 months, * Then, ½ cm/month during the 2nd 9 months of age.
Head circumference
closes by 6-8 weeks of age.
Posterior fontanel
closes by 12-18 months of age.
Anterior fontanel
Diamond in shape * The junction of the sagittal, corneal and frontal sutures forms it * Between 2 frontal & 2 parietal bones * 3-4 cm in length and 2-3 cm width * It closes at 12-18 months of age
Anterior fontanel
- Triangular * Located between occipital & 2 parietal bones * Closes by the end of the 1st month of age
Posterior fontanel
It is 30.5 to 33cm (usually 2–3cm less than head circumference). By the end of the 1st year, it will be equal to head circumference. Physiological growth of infants:Pulse 110-150 b/min Resp 35 ± 10 c/min Breath through nose. Blood pressure 80/50 ± 20/10 mmHg
Chest circumference
- Pulse ( 120 to 160 b/min ). - Radial pulse is normally absent, if prominent suspect that there is PDA
- femoral pulse is normally palpable ,if (-) suspect Coartationof Aorta - Respiration ( 35 to 50b/min) .
Vital signs
Pulse
( 120 to 160 b/min ).
Respiration
( 35 to 50b/min) .
Temperature
(36.3 to37.2C ).
taking is done only once to rule out imperforated anus.
Rectal temperature
– dangerous failure to pass meconium after 24 hrs, abdominal distention, foul odor breath, vomitus of fecal material which might result in aspiration and cause respiratory problems.

DIASTOLIC 40 TO 55 MM HG
Eruption of teeth starts by 5–6 months of age. It is called “Milky teeth” or “Deciduous teeth” or “Temporary teeth”.
TEETH
recognize an object in the midline of their vision ,1-month-old infants see black and white patterns.
One-month-old infants
focus well (from about age six weeks) and follow objects with the eyes (although still not past the midline).
Two-month-old infants
Three-month-old infants
can follow an object across their midline.
recognize familiar objects, such as a frequently seen bottle, rattle, or toy animal.
At four-month-old infants
infants are capable of organized depth perception
Six months,
children pat their image in a mirror.
On seven-month-old
, an infant looks under a towel or around a corner for a concealed object (beginning of object permanence).
By ten months
is demonstrated by the 1-month-old child who quiets momentarily at a distinctive sound such as a bell or a squeaky rubber toy.
Hearing
has emerged as an essential modality for the facilitation of growth and development; positive effects of supplemental mechanosensory stimulation have been demonstrated in a wide range of organisms. An infant needs to be touched to experience skin-to-skin contact. Is promoted to have close physical contact.
Touch
begin forming early in fetal development. It is known that babies prefer sweet tastes over sour or bitter tastes. Infants demonstrate that they have an acute sense of taste by turning away from or spitting out feelings they do not enjoy.
Taste buds
can smell accurately within 1 or 2 hours after birth. They respond to an irritating smell by drawing back from it. They appear to enjoy pleasant odors and learn early to identify the familiar smell of breast milk
