What is the standard weight for a two-month-old infant?

Under normal circumstances, a 2-month-old boy typically weighs between 4.4–7 kg and measures 55–63 cm in length, whereas a 2-month-old girl usually weighs between 4–6.6 kg and measures 54–62 cm in length.

For full-term infants, weight gain is especially rapid during the first three months after birth, with an average monthly increase of approximately 800–1,200 g. However, growth patterns vary among individual infants, and actual development may differ accordingly.
