I'm interested to know if you have actually used the same nappies on two children. I only had a small stash for my first son - maybe 15 nappies? - and he was only in cloth for 18 months, and I didn't even use them full time. He was often naked or in terry flats (summer lasts for 11 1/2 months here, so we can get away with that ). Several nappies were had it before he was finished with them.
Only three survived him and then two years of storage: my three BBH fitted. They had been my favourite nappy, so I used them more than anything else. I got another nine months of only at-home use with baby number two before they were so misshapen they wouldn't stay on and I through them out. They had in excess of 350 washes.
My second boy has 18-20 nappies, and is naked more than his brother was. He's been in full time cloth since they started to fit - so far 14-15 months. We stopped using cloth overnight a few months ago. I wash every 3 days, and rarely run out. Already one nappy is just about had it. I wrecked one Itti Bitti AIO by hanging it incorrectly on the line. At least one other nappy is going to be had it by the time he's finished with them.
We're having one more baby in October. I had been thinking that we'll just use up and wear out whatever nappies we had left from DS2 (hoping he'll be out of nappies by then ), and the pile of terry flats that get used occasionally. Then just fill in the gaps when we go out with disposables. But now I'm thinking that maybe that won't be an option because my nappies probably won't last that long.
Have many of you really got use for 2 kids out of your nappies, and has it only been done by having a stash of 30 or more nappies?
