We also are 7th gen 'devotees'! I first used them when my (now 9 m/o) was a newborn (after smelling the horrible pampers chemical "baby" smell that they gave, of all places, at the hospital). I came to distrust other diapers especially since baby had those great newborn poop blowouts. 7th gen stayed on more snugly at that time -or something-.
After my local super stopped selling them I went to Huggies 'natural fit'. Soon I started the deal on Amazon subscription (get 20% off + free shipping!_ they just show up when you request them, even if sooner than a month, on the doorstep).
After trying them for 3 months or so, we are totally back to the 7th gen. They are even "cut for babies not shaped like a brick" lol- but seem to fit better, no weird chemical smell. Can't speak for their decomposition- but the fact that they are so soft and not chemically is good enough for me. And no problems handlind the good- ol' POOPS!
Looking at my bill, the price worked out to .28 per diaper.
