Size Chart | Thirsties Baby
Our sizes are very generous. Resist the temptation to size up! Buying a diaper or cover that is too large, will end up leaking. *Note, our x-small size is perfect for the average size newborn baby and will fit thru the first 2-3 months. Hoping to skip a size? Large may be the one to go without. Many babies can wear their mediums all the way to potty learning.
