our guide to
Sizing
Earlybirds sizing is based on the weight of your baby, not on the zero e.g. 0000 method. Our research has indicated this weight system is more accurate in ensuring that the size you have chosen will fit your baby perfectly.
Find the right size for your baby by selecting their current or future weight.
