Answer:
28 pounds
Step-by-step explanation:
In the first year of life, the pediatrician monitors the baby's weight gain, as this phase is fundamental for its development. In the first two months, he gains more weight than ever. As it grows, the pace slows down.
In a healthy baby with adequate levels of nutrition, it is normal for the weight to triple by the end of the first year of life. Following this principle, at 2.5 years of age, the baby's weight should quadruple, considering that this baby is healthy and consumes adequate levels of nutrition. Thus, if the baby was born weighing 7 pounds, to stimulate the weight this baby would have at 2.5, we should multiply 7 by 4. So 7 multiplied by 4 equals 28 pounds, so we can conclude that at 2.5 years old the baby will weigh 28 pounds.
