Um, only if you plan on washing once a week! If you wash every day or two, you can start with 20-30 (thats leaving some room for poo-spolsions and missing a washing day). If money is a huge issue, you can always try pre-folds for the newborn size and then move on to OSFA (one size fits all) nappies.

I think I have almost 70 nappies all up. But thats including about 40 fitteds of various sizes, and a handful of covers, that we used from between birth and 12 months, and I think we have about 24 large itt bittis that we've been using for the last year and a bit. Plus some dedicated night nappies.

I soak in water, but that's my partners issue. I'd prefer to dry pail, and I've heard it's better for the nappies (though ours are still fine with soaking so I don't really know how much truth there is to it). Most people dry pail, but you do have to rinse the urine off bamboo because if you leave it for mroe than 24 hours (I think) it starts to eat the bamboo (so I've read). We used liners to start with, but as she got older her poo became easier to roll into the toilet.

When Jazz was in full-time cloth (she's toilet trained/ing so there only one nappy a day now) we washed every second day, and never really ran out of any nappies. If you're running out then do a load of washing. Not too tricky, and the washing is easy since the washing machine does it all

As for night nappies, thats a really individual one. When she was a newborn I changed her as often during the night as I did during the day. This worked for us since Jazz woke every 1.5-2 hours and wee'd pretty much every time. As she got older I bought night nappies, which are more absorbant and dry the moisture away so we didn't have to change as often. If I knew she was wet or had done a poo I'd change. That's still pretty personal though, I've had people with strong opinions tell me leaving her in a nappy all night is neglect But she would have been in the same one all night if she was sleeping through anyway so You'll get to know their weeing and pooing habits.
