A baby's brain triples in size during the first year of life.
✓ TRUE FACT
A newborn brain is roughly ~350–400 g, and by age 1 it can reach around ~900–1,000 g, which is close to “tripling” in mass. This growth is driven by rapid synapse formation, myelination, and overall brain tissue expansion. It’s one reason the first year is such a critical window for sensory and language development.
