This is a 10 day old, 7.5 pound baby in size newborn. She has almost outgrown it already. It's a very nice cover on small newborns and preemies. Use Preemie size Prefold Diapers under this. Even Orange edge newborn diapers are a bit much under this tiny cover.

Size small on 9.5 pound baby

Above is a size small on a 8 week old 9 pound 14 ounce baby

For cord healing, it is easy to fold down the top part of a Bummi Original (or Bummi Cotton) size small.

This baby is 5 weeks old but almost 12 pounds already. He's really big! He is also in the Bummi Original size small. Under this is the infant prefold folded the "alternative fold". This is the trimmest way to cloth diaper a newborn. The picture below is the diaper on this baby. A quick, easy, trim fitting, and very economically priced newborn diapering system.

12 weeks, 13 pounds size small

same baby as above,12 weeks, 13 pounds, showing what is under it which is an orange edge newborn prefold, unfastened, folded in thirds. A very trim way to cloth diaper.

In a size small, instead of orange edge newborn prefold, this shows a green edge infant size prefold folded the other way; the "alternative fold".

Original size Medium with an unfastened Infant Prefold under it. Age 4 months, 18 pounds.

Same as above, size Medium with Infant Prefold under it. Age 4 months. 18 pounds. He also fits a large already - see below.

Same as above but this time in a size Large with a Premium Prefold under it.

Since this baby fits both sizes now, mom uses the medium with the infant prefold when she wants a trim diaper, and uses the large with the premium prefold when she wants more absorbency. Some will ask, "How'd you get a Regular Premium prefold on a 4 month old? Those diapers are huge!"
Yes, they are big diapers for a 4 month old. Most 4 month olds are in infant size prefolds. This baby is larger than average. See how it's done below.

Lay baby on this and close it up. All done!

Alternative fold - can be in thirds or fourths: middle step is optional

Bummi Original is nylon outside. Bummi Cotton is the same cover but with a cottony outer sewn over the nylon.

See more pictures here.

This is great over unpinned prefolds, but please don't try to use it over fitteds since it is narrow at the hip. This is the trimmest of the wrap style covers.
