Best practice
Pair this phrase with verbs like 'spend', 'influence', 'shape' or 'navigate' to clearly define the relationship between the time period and the individual's growth.
Common error
Avoid the common mistake of saying "early developmental years of a child's childhood". Since developmental years inherently refer to childhood and adolescence, 'of a child's childhood' is redundant and weakens your prose.
