Also, if they're wearing stuff that's too big, you can roll up stuff a bit easier when there's no feet.

We bought a few of each... and DS was 7lb 70z and wore the 0000's for a good month or so. I just made sure I bought super cheap stuff for the 0000's in case I didn't get much use out of them. The Bonds nighties are awesome in terms of sizing - they're so simple that there's more margin for size variation to fit any size/width. He could actually still fit into 000's or even 0000's in the nighties at 4 months (and he was 7.6 KILOGRAMS by then!) and wearing 00's or 0's in the daytime!!!!

I must admit, I was all thumbs to start with and I found that using clothes that fit him a bit better was easier for a klutzy nervous first-time mum!
