My favorite nappy is the 'Pop In' nappy.

* It is a one size fits all.
* It has double leg gussets (which is great for runny newborn poo, if you plan on using with a newborn).
* It has velco waist tabs.
* It is however a all-in-two which basically means that you snap in the boosters and they unsnap to wash and dry, this does mean that they dry quicker than if they were a all-in-one.
* You can buy an extra booster that makes it into a night nappy (I have not done this myself but I will when DD2 arrives).

They are about $36- each but well worth it if you ask me.
(I am not sure if Mel (Arimeh) has any left but she did have them on special in her store.)

At the end of the day it does depend on your baby/child as they really are all different. This nappy however is the only nappy that I have NEVER had a leak from even on long trips and I see will be suitable for both my DD and newborn to share, there are alot of OSFA nappies on the market that really would not be suitable for newborns.

I strongly suggest that if you are in no hurry find the nappy you most want to try and buy 1 or 2 and try it our before spending alot on nappies that may not work for you, then if they work - buy up big!

Good luck .
