Growth & Devpt - During age 6-12 MO

Growth & Devpt - During age 6-12 MO

PHYSICAL DEVELOPMENT.

Growth slows

sit unsupported (about 7 mo) and

to pivot while sitting (around 9-10 mo) – can handle  several objects at a time

pincer grasp (around 9 mo

begin crawling and pulling to stand around 8 mo

walk before their first birthday either independently or in a walker.

Motor development correlate with increasing myelinization and cerebellar growth.

Tooth eruption occurs, usually starting with the mandibular central incisors

Tooth development reflects skeletal maturation and bone age

Cognitive development.

New object is picked up, inspected, passed from hand to hand, dropped, and then mouthed

A major milestone is (about 9 mo) object permanence (constancy), the understanding that objects continue to exist even when not seen.

At 4-7 mo, infants look down for a yarn ball that has been dropped but quickly give up if it is not seen.

With object constancy, infants starts searching, finding objects hidden under a cloth

Emotional development.

Child looks back and forth between a stranger and parent, may cry.

Separations become difficult.

At night begin to awaken cry.

Does not like to be fed, turns face away as the spoon approaches.

Self-feeding with finger =the pincer grasp

Tantrums appears = conflict with parental controls

Communication.

nonverbal communication, responds to vocal tone and facial expressions.

picture books is ideal for verbal language.

Implications for parents and pediatricians.

Teach about  introducing finger foods or drinking from a cup (before first birthday)

Poor weight gain at this age = struggle between an infant and parent during infant's eating.
