Ultra Preemie

~3–5 lb (1.6–2.3 kg)

Ultra preemie sizing is designed with a snug fit through the arms and core, with a touch of extra leg length to allow room during early, unpredictable growth spurts. 

Preemie

~5–7 lb (2.3–3.2 kg)

Designed for babies who are still smaller than newborn sizing but need a bit more room than ultra preemie garments. This size offers a comfortable balance of softness, stretch, and everyday wearability.

Newborn

~7–9 lb (3.2 –4.1kg )

Designed for babies who have outgrown preemie proportions and are ready for a more traditional fit. Newborn pieces offer additional length and room while maintaining softness and comfort.

Fit Notes

• Our fabrics are soft with gentle stretch
• Clothing should feel secure, not tight
• If unsure, choose the size that allows the most natural movement
