Our Guide to Sizing is Based on Weight

Earlybirds garment sizing has been designed according to baby's weight, not on the zero '000 method like many other brands. We have found the '000 method is not accurate and in most cases the garments are too big for the baby, making them look smaller and uncomfortable. Our research proved the weight system to be more accurate in ensuring that the size chosen will fit your baby perfectly.

Small: 1lb13oz – 3lb 5oz,
Medium: 3lb 5oz – 5lb 9oz,
Large: 5lb 9oz – 7 lb 12 oz,
XLarge: 7lb 12oz – 9lb 15oz
