Growth during the first year • An average healthy baby gains 1-2 lbs. each month during the first six months of life. • The average infant weighs 20-22 lbs. at the end of the first year and is 30” long.
Patterns of development--examples • Head to toe: lifting head to see object, then picking it up, then walking to it • Near to far: Waving arms, grabbing objects with palms, picking up objects with thumb and forefinger • Simple to complex: Sucking, eating with fingers, eating with utensils
Growth vs. development • Growth: increase in size • Development: increase in physical, cognitive, emotional or social skills
Proportion • Definition: size relationship of one thing to another • Example: baby’s head and abdomen are larger compared to adults
Depth Perception • Definition: ability to recognize that an object is 3-dimensional not flat • This skill is first noticeable in infants at 2 months. • By 3 months, infants prefer to look at three dimensional objects.
Hand-eye Coordination • Definition: The ability to move the hands and fingers precisely in relation to what is seen • Infants exhibit this behavior at around 3-4 months as they reach for objects • This skill continues throughout childhood
Senses • Hearing is the most developed sense at birth. • Sight, smell and taste are the least developed • What accounts for this? Prenatal development…think about “How does your baby grow?”
Hearing problems??? These signs would indicate a possible hearing problem in an infant… • Not startled by a clap • 3 month old doesn’t turn toward a voice or sound • Not awakened by loud noises or respond to ordinary noises
Motor Skill Development Why may one infant’s motor skills develop more slowly or more quickly than average? • Individual rate • Experiences • Encouragement
Infant care • Always hold the head and neck because an infant does not have the muscle support to hold it up on its own…until around 3 months. • Avoid putting a bottle in the crib so that the baby can suck and drift off to sleep more comfortably because…. 1. Choking 2. Ear infections 3. Associate milk with sleep 4. Tooth Decay
Weaning Process of changing from breast/bottle to a cup Happens around 9-12 months Remember breast milk or formula is the main source of nutrition during most of the first year.
Teething Primary teeth usually appear around 6 months. Symptoms: Swelling gums, cranky, restless, wakeful, drool, lower appetite, fever, coughing and diarrhea Helping your infant with teething… • Teething rings (cold, not frozen) • Cool cloth • Rubbing ice on gums • Commercial medication
