2 lo's on cloth - we HAVE to wash every other day, cant get away with anymore than that. Both lo's are changed upto 5 times on average per day. WHen they were younger though, we washed everyday - there was just no getting round it, was a right pita, but doesnt last long.
We also use night nappies.
As for re-doing ur stash I would keep what u have, as when the lo's change shape and their appetites for food instead of milk increases, the'll probably work. Thats what happened with us
And yes, its sods law!!!!!
