Charlie Banana is One-Size, right? Probably too big until the babe is 6-10 weeks old, based on what I know (disclaimer-- I am a FTM and no one in my family has CD'd for 30 years-- I learned everything I know from diaperswappers.com).
By the time your babe is not a newborn, you can probably get away with 10 per day or so, maybe 12 to be extra safe. So, multiply that by how often you'll do laundry (20 for every 2 days, 30 for every 3, etc.) From what I understand 12-18 per day is better for newborns, but you will probably need newborn-sized diapers for that, as most OS, though they claim to fit from birth, don't. NB sized diapers don't seem like a great investment, which is why a lot of people do sposies or a service for the first couple of months, but they have great resale value. Probably tough to sell from Singapore, but I think you said you'll be moving back to... the US? When your babe is a couple months old?
Anyway-- TL;DR, visit (and search) Diaper Swappers for more good info.
