Choose the correct growth and development milestones for each age group.

Motor Skill Development by Age.

Please choose only one age group for the milestone for each age.

(One X per row).

Choice A rationale

Babies at around 6 months are developing object permanence and might experience anxiety if they cannot see familiar faces, such as their mother's due to the mask.

Choice B rationale

Hunger is a common cause of crying in infants but doesn't specifically relate to the scenario provided regarding the mask.

Choice C rationale

Cold can cause discomfort in infants, leading to crying, but this is more of a general response and not directly related to the mask scenario.

Choice D rationale

Stress can cause crying, but the specific trigger in the scenario is the mother's masked face, causing potential anxiety.

Choice A rationale

A 6-month-old infant typically grasps objects voluntarily, which is a normal developmental milestone.

Choice B rationale

The posterior fontanel usually closes between 2 to 3 months of age, so it being closed at 6 months is normal.

Choice C rationale

It's expected for an infant's birth weight to double by about 5 to 6 months of age, indicating healthy growth.

Choice D rationale

Head lag in a 6-month-old indicates a delay in motor development and should be reported as it can signal neurological issues.
