Most infants triple their birth weight by 4 to 6 months of age and quadruple their birth weight by the time they are 1 year old.
By 6 months of age, the infant's brain weighs half that of the adult brain; at age 12 months, the brain weighs 2.5 times what it did at birth.
The head circumference increases rapidly during the first 6 months: the average increase is about 1 in per month.

A. The heart triples in size over the first year of lifE. While cardiac growth occurs during infancy, the described change is not specific to a developmental milestone.
B. Most infants triple their birth weight by 4 to 6 months of age and quadruple their birth weight by the time they are 1 year olD. This statement accurately describes a significant developmental milestone related to physical growth during infancy.
C. By 6 months of age, the infant's brain weighs half that of the adult brain; at age 12 months, the brain weighs 2.5 times what it did at birth: This statement describes brain growth rather than a
milestone related to physical growth or development.
D. The head circumference increases rapidly during the first 6 months: the average increase is about 1 in per month: While head circumference growth is important, it does not specifically relate to the described developmental milestone of weight gain during infancy.

Correct Answer is A
Explanation
A. "Keep a night light on in your child's room." - This option addresses the child's fear of
monsters by providing a solution that offers comfort and reassurance without dismissing the child's concerns outright.
B. "Let your child sleep in your bed with you." - While this may temporarily alleviate the child's fear, it doesn't address the underlying issue or help the child learn coping mechanisms for dealing with fear.
C. "Tell your child that monsters are not real." - This response invalidates the child's feelings and may increase anxiety by dismissing their fears as irrational.
D. "Stay with your child until the child is asleep." - While staying with the child may provide comfort initially, it doesn't offer a long-term solution and may reinforce the fear by implying that there is something to be afraid of.
