Im 31 weeks and have gone with pampers. 1. Because I'm trusting a well known brand (I know, I know they're plenty of cheaper brands but I want one that's been about a while) and 2. Both dh and I have sensitive skin so we have opted for the pampers sensitive nappies. Now from looking at the sizes, the 1's & 2's don't have much difference in size. I only have about 40 size 1's but bought 4 packs of size 2's yesterday in kiddicare. Is there a huge difference?!
