My tip is to try Gumtree, or the secondhand nappies from here, or FB groups. I picked up heaps for a bargain price and could then figure out what worked best for us.

I started with DD2 two years ago and I picked up the lingo, but not quite the obsession. I like to not spend a fortune and I'm not that fussed on really pretty or 'special' ones (have some secondhand). But I'm def going to get my money's worth as there's plenty for DD3.

I did prefer the tiny ones for newbies too. Esp since my NBs are really small. And night nappies are also great when they're a bit bigger.
