i started out with just enough to get me for a day and a bit so with washing every day (including some pockets so i had something dry within a few hours of washing), i had just enough to keep me out of sposies, then i added to them a few at a time til i had enough to last for three days - and then i came here and my frugalness was forgotten
to start out cheaply, something a dozen flanny flats with some pookey pockets would be great, as they are really absorbant, cheap and dry fast - what more could you want? Peapods are also nice and cheap for a starter too - esp considering they come with an insert.
with patrick i started out using flanny flats with weenies pouches (the old ones), which was a really cheap system, but i had lots of leaks at horrible times - so never used them out of the house and never at night.
and yes the wipes is a fantastic way to save money - i bought some commercial brand baby facewashers when patrick was born - soft baby terry not like towels (playgro i think) - they were the more expensive ones, about $8 for 6, but nearly four years later they are still going strong, so have saved us heaps over that time
