? about prefold sizes

aschleser

Here's my question - I bought a dozen small prefolds off of tinytush.com - it says they are 13.5x14.5 in size (I am almost positive this was BEFORE they are washed) - they seem small.  It says they fit 7-18 pounds.

GreenMountainDiapers has newborn prefolds that are  12.5x13.75 unwashed - and fit 5-10 pounds.  Their small prefolds are 14.25x16 when new, and fit 10-15 pounds.

It seems there are vast differences in sizes and how big a baby they should fit.  So - should I treat the tinytush as a newborn size when building my stash?  Has anyone used the tiny tush prefolds before?

I feel like they may fit a little longer than GMD newborn, but not as long as 18 pounds, they look so little now that I've washed them.
