How to choose
Use height as your primary reference. If your baby is between sizes, choose the larger one — the bodysuit should not pull along the length.

Baby Bodysuits · Size Guide
Choose size primarily based on height. Age is only a guideline and may vary significantly. If your baby is at the upper end of a range or wears a diaper, consider sizing up.

Newborns
Size 56 is often outgrown quickly. If your baby is close to or above 56 cm, it makes sense to start with 62.
Fit & diapers
Bodysuits fit tighter with a diaper. A small amount of extra length improves comfort, especially in the lower part.
In practice, it’s best to have two adjacent sizes: one for now and one to grow into. This reduces the risk of items becoming too small after washing or a growth spurt.
