How long is a 3 month old baby?

The length of a 3-month-old baby typically ranges from about 23 to 25 inches (58 to 64 cm), although individual growth can vary. Most babies grow at a rate of about 1 to 1.5 inches per month during their first few months. It's important to remember that growth patterns can differ among infants, so some may be slightly shorter or longer. Regular check-ups with a pediatrician can help track a baby's growth and development.
