These measure 14 inches at the wings by 16 inches in length. I definitely recommend using the size that your baby is in. You can find that by measuring their waist and rise (belly button, between the legs, and up to the the waist on the back).
These have been sanitized, washed in Beyond Clean, and softened with Beyond Soft! Ready to go on baby's bum bum!
Please note the small stain on number 5. It has been reduced in price for that matter.
