The early child period is considered to be the most important developmental phase throughout the lifespan.
Some age-related development periods and examples of defined intervals are: newborn (ages 0â4 weeks); infant (ages 4 weeks â 1 year); toddler (ages 1â3 years); preschooler (ages 4â6 years); school-aged child (ages 6â13 years); adolescent (ages 13â19).here appear to be six major stages in which a childâs acquisition of syntax develops. First, is the use of sentence-like words in which the child communicates using one word with additional vocal and bodily cues. This stage usually occurs between 12 and 18 months of age.
