How to measure: Sizes are by age. For the best fit, check your child's height and weight against the chart below — these matter more than age alone. Measurements in inches and pounds.
| Size | Age | Height (in) | Weight (lb) |
|---|
| Newborn | 0–1 mo | 18–21.5 | up to 9 |
| 3-6M | 3–6 mo | 24–26 | 12.5–16 |
| 6-12M | 6–12 mo | 26–29 | 16–21 |
| 12-18M | 12–18 mo | 29–31.5 | 21–25 |
| 2T | 2 yr | 33.5–35.5 | 28–30 |
| 3T | 3 yr | 35.5–38.5 | 30–33 |
| 4T | 4 yr | 38.5–41 | 33–36 |
| 5Y | 5 yr | 41–44 | 36–41 |
Fit tip: Our pieces run true to size with a little room to move. If your child is between sizes or you'd like extra room to grow, size up.
