Size Guide

⭐ Battesimo Size Guide (0–24 Months)

Accurate measurements = perfect fit for your little one.

We recommend measuring your baby rather than choosing by age — every child grows at their own pace.

🧵 How to Measure Your Baby

1. Height

Measure from the top of the head to the heel (no pointed toes).

2. Chest

Measure under the arms around the fullest part of the chest.

3. Front to Crotch

(For rompers, onesies & suits)
Measure from the front collar down to the bottom of the crotch.

4. Foot Length

Useful for choosing booties.

5. Head Circumference

Measure around the widest part of the head.
