The heart triples in size over the first year of lifE. the average pulse rate decreases from 120 to 140 in the newborn to about 100 in the 1-year-old.
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.
The Correct Answer is B
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 D
Explanation
A. Ignore the temper tantrums. - Ignoring tantrums may work for some children, but it's not a universal solution and can sometimes escalate the behavior. It also doesn't teach the child appropriate ways to cope with their emotions.
B. Tell the child that temper tantrums are not acceptable. - While setting boundaries is important, simply telling the child that tantrums are unacceptable without providing alternative coping
mechanisms may not be effective, especially for a toddler who may not fully understand verbal reasoning.
C. Restrain the child physically. - Physically restraining the child can be harmful and is not recommended as a method for handling temper tantrums. It can lead to increased frustration and potentially cause injury to the child.
D. Distract the child by offering to play a game. - Distracting the child with a game or other engaging activity can help redirect their attention away from the tantrum and towards a more positive outlet for their emotions. This approach can be effective in diffusing the situation and teaching the child healthy coping strategies.
