They're all pretty much good. So here's my suggestion....

List all of the diapers you are thinking of buying. Make the list a good bit random. Number the list from 1 to however many diapers you are thinking of buying.

Then let the Google Random Number Generator pick a number between 1 and the number of diapers. It's easy to use -- just type "random number generator" in Google and it should come up.

Run the random number generator, and whichever number it comes p with, go to that number in the list and that's your choice.

For example, here's a list of 5 diapers I have on hand that I may want to wear tonight to bed:

1. Rearz Safari
2. Trest Elite
3. NRU Str8Ups
4. Tykables Unicorns
5. Crinklz Buccaneer

This list is fairly random, so now let Google give me a number between 1 and 5......and it chose 2. So the diaper of the night is Trest Elite.
