when should babies double their birth weight

Babies typically double their birth weight by around 4 to 6 months of age. Most healthy, full-term infants reach this milestone closer to 4 months, though some sources note the average as around 5 to 6 months. The exact timing can vary depending on factors such as whether the baby is breastfed or bottle- fed, with bottle-fed babies sometimes doubling their weight earlier than breastfed ones.
