Hi just wondering what the general birth weight is to be expected for twins?

I will be using cloth nappies and am looking at getting premmie size pre-folds and then some one size nappies, so just wondering what the general weight range is.

I have had a 8pd-3.6kg baby 3 weeks early, then a 7pd9-3.4kg baby 2weeks early and am expecting early again as I will be having a scehduled cs due to being unable to birth naturally.

All help and comments greatly appreciated

Love
