Infancy lasts from birth to the 2nd birthday • For the first 28 days after birth, the infant is referred to as a neonate • The neonate undergoes significant adaptations to help it survive outside the uterus
ADAPTATIONS OF THE NEONATE • The neonate’s lungs take over the part of circulation and oxygenating the blood – 2 shunts close over and allow the blood to flow to the lungs instead of the placenta • The neonate takes its first breath (usually within 10secs after birth) – this makes the blood stream absorb the fluid in the lungs and allows them to fill with air
Before birth, the neonate receives nutrients from the mother via the placenta – after birth the neonate has some fat supplies but must rely on regular feeding in order to grow and develop • Colostrum from breastmilk (secreted in the first few days after birth) supports nutrition and boosts immune function
The excretory organs become functional and capable of eliminating waste products at birth – meconium is excreted rather than faeces for the first few days • Maintenance of body temp goes from being kept stable whilst in the uterus - to be needing to be regulated by other forms eg clothing, blankets, environment
THE APGAR TEST • APGAR is an acronym for Activity, Pulse, Grimace, Appearance and Respiration • It is usually the first test given to newborns • It is administered twice – at 1 minute and 5 minutes after birth
A neonate receiving a score of 7 or above 1 min after birth is said to have successfully adapted to life outside the uterus • If a score is below 7 or after 5 mins has not reached 7 medical attention may be required
PHYSICAL DEVELOPMENT • 2nd fastest period of physical development (behind prenatal only) • Birth weight doubles by 6mths and triples by 12mths • Bones continue to ossify • Senses develop further • Reflexes that are present at birth begin to change to more controlled movements (motor skills)
SOCIAL DEVELOPMENT • Family is the most significant influence on social development • Infant is totally dependent on caregivers – some social skills are learnt through observation • Infant can smile around 6 weeks and recognise facial expressions by 6mths • Basic games by 6mths • Many social skills are developed through play (sharing etc) and learning of acceptable behaviours ( no biting/hitting)
EMOTIONAL DEVELOPMENT • Emotional development centres around the family • Able to be comforted when hurt • Emotional attachment formed with caregivers/parents within 3-4 months – which assists in feelings of security, trust and safety • Infant may become distressed when primary caregiver leaves the room – separation anxiety • By 8mths the infant can show anger, happiness and frustration (temper tantrums)
INTELLECTUAL DEVELOPMENT • From birth all senses are present and therefore the infant is capable of learning • Within months the infant will recognise its name and will respond when called • This progresses to names of favourite toys, people and objects
Infants learn cause and effect quickly – crying results in attention • Object permanence becomes apparent • By 18mths infants can imitate and pretend – talk on phone • Language development is rapid – 3mths sounds (goo googa-ga), few words by age 1 (mum, dad) • By the end of infancy the child can say approx 150-300 words
