Question 1

At what age should a child be able to walk independently without support?

Accepted Answer

By 12-15 months of age. Walking independently is a gross motor milestone expected by 15 months; absence of this skill warrants developmental evaluation.

Question 2

According to Erikson, what is the primary psychosocial task of a toddler (ages 1-3)?

Accepted Answer

Autonomy vs. Shame and Doubt. Toddlers strive to develop independence and self-control; allowing choices and consistent boundaries supports healthy development.

Question 3

What is the expected birth weight doubling and tripling timeline for a healthy infant?

Accepted Answer

Birth weight should double by 4-6 months and triple by 12 months. Failure to meet these benchmarks may indicate a feeding problem or underlying illness.

Question 4

At what age does a child typically develop object permanence, and what stage of Piaget's theory does this correspond to?

Accepted Answer

Object permanence develops around 8-12 months during Piaget's Sensorimotor stage. The child understands that objects continue to exist even when out of sight.

Question 5

What is the average age at which an infant should produce their first recognizable word?

Accepted Answer

By 12 months, an infant should say at least 1-2 recognizable words such as 'mama' or 'dada' with meaning. Absence of any words by 16 months warrants referral.
