how many diapers and what size?

Katie
I'm starting to collect diapers because it's the only baby thing I can buy at the moment. (We don know the gender and have an agreement to wait until January for big stuff.) I'm just wondering how many is too many in a size? If it matters I was an 8lbs baby and he was a 12 pounder, so I figure we are likely to have a chunky a monkey.
