| Weight (3rd–97th) | Length (3rd–97th) | Head (median) | |
|---|---|---|---|
| Boys | 8.5–12.9 kg (median 10.5) | 75.4–85.1 cm (median 80.2) | 47 cm |
| Girls | 7.8–12.5 kg (median 9.8) | 73.3–83.9 cm (median 78.6) | 45.9 cm |
Any steady curve within this range is normal; what matters is that your baby follows their own curve over time.
