Hi Mards,

I personally wouldn't go for a fitted nappy when the baby is newborn. Especially a nappy like a BB which is "birth to toddler" as its best fit will more than likely be in the 5-12kg range.
What I found worked really well for us was using prefolds and covers for the first 6 weeks or so, and then when bubs got up to about 4.5kg, starting to use a combination of pockets, fitteds, and more prefolds.
The other thing I did in the first few weeks was alternate cloth and disposable, soI got about 6 prefolds, and covers, plus I had a few flanny flats, and I used those in one day, and then when they were in the wash and drying the next day, I used sposies. Eventually I got to the stage where I was only having to use about 3 disposables each cycle before being back into cloth.

This was a great system for me - prefolds are so cheap, and a good cover is a life saver for breastfeeding poo. They just catch everything! It was no guilt cause I was using cloth from birth, but I knew that at any time if things got too much, I would have some emergency sposies there just in case.

If you want to do something like this, I would recommend maybe getting 12 prefolds or flanny flats, and mayeb 3-4 covers (something like a small bummis super whisper wrap) and then maybe get a few small fitteds. From about the 5kg mark when bubs is putting on some good fat (maybe 6-8w old?) you can start using your "one size fits all" and that is when you want to have say 12-20 odd nappies for full time cloth.
