Erm this cloth buying is going to be hard lol

Another ? or two (sorry your all going to be mighty sick of me soon) -
Whats the difference between night nappies and 'day' nappies? My boys always wake up with sposies choc full of wee so if I used cloth for nighttimes I would need something mega absorbent or easily boosted so they dont wet through.

Can you interchange inserts? I have some of the BBH inserts etc for my bumG pockets, will I have to turf them and start again or could I use them with whatever I buy, provided they are pockets?

As for drying nappies, are any of them mega hard to get dry? Obviously not a total issue up here as its super hot and things dry within an hour of being on the line (we own a dryer just in case though) but it would be a factor in what I end up buying.

Also, is it hard to resell MCNs? Because Gage is our last bub so if I MCN him from birth (and my bubs grow fast!) and buy newborn size nappies then I'll be lucky to get maybe 8wks of use out of them before they are relegated to the cupboard forever. Id have to resell them to make it worth my while. Unless there is a nappy that fits newborns to say 8kgs so I wouldnt have to change sizes?

Ok I'll back away now lol
