At what age does a child reach 4x their birth weight?

A child typically reaches four times their birth weight by around 2 years of age. This milestone is part of the normal growth and development patterns observed in pediatric patients. During the first year of life, infants grow rapidly, usually tripling their birth weight by about one year. Following that period, the growth rate begins to slow down, with significant but steadier weight gain continuing into the second year.

By 24 months, a child's growth trajectory leads them to achieve approximately four times their birth weight. Understanding these growth milestones is important for healthcare providers and caregivers as they monitor developmental progress and nutritional needs in young children. The other age options do not align with this typical growth pattern, making the choice of 2 years the most appropriate answer.
