A toddler is expected to weigh four times the birth weight at what age?

The correct answer is that a toddler is expected to weigh four times the birth weight by 24 months of age. This milestone aligns with typical growth patterns observed in young children. Most infants gain weight rapidly in their first year, tripling their birth weight by around 12 months. By 24 months, growth continues, and it is common for children to reach four times their birth weight as they transition into toddlerhood. This growth is crucial for their development and correlates with other milestones in physical and cognitive growth during the early years.

This understanding of growth patterns reflects pediatric health guidelines and can aid in monitoring a toddler's development to ensure they are on track with their growth benchmarks.
