When we first started using gDiapers for our daughter in 2007 you could only order the “little g” pants directly from gDiapers and very few places carried the inserts. I just noticed that BabiesRUs stores are now carrying the individual pants at some locations.
I recommend buying the “little g” pants with the starter kits as they are much cheaper. However once you start using them and your spouse sees how “cute” the non starter kits pants are, you’ll be looking for a place to buy these individually. BabiesRUs is the only store that I know of around here (Delaware) that carries them individually. Best of all you can save on shipping and pick it up at your local BRU if they stock them.
