At 18 months most toddlers walk well, say several words and love to help.
These are things most children (about 3 in 4) can do by this age. Babies born early may reach them later — use their corrected age.
| Weight (3rd–97th) | Length (3rd–97th) | Head (median) | |
|---|---|---|---|
| Boys | 8.9–13.5 kg (median 10.9) | 77.2–87.3 cm (median 82.3) | 47.4 cm |
| Girls | 8.2–13 kg (median 10.2) | 75.2–86.2 cm (median 80.7) | 46.2 cm |
Any steady curve within this range is normal; what matters is that your baby follows their own curve over time.
