I would highly recommend going with gDiapers.
I don't like and use the flushable inserts either and use organic cotton trifolds instead. I have been using this system for a year now with my daughter and love it.
The nice thing is that you can reuse parts of the diaper if it did not get wet. in contrast to the pocket ones where you need to change the whole thing. gDiapers have a snap in liner, it is easy to unsnap and reuse the colored outside again. The other is that they are all cotton - all but the part that holds the trifold. So there is no polyester on babys skin.
The right number for me is 12-15 gDiapers and 25 cotton inserts.
I knew it needed to be a simple system to keep going and for me it has been.
either way, good luck! :)
Congratulations on your choice, not only will your baby feel better you are also doing a favor to the environment!
sincerely,
C.
