Any thoughts on how to boost a prefold for night use?
for a newborn - lay inside the prefold a nb sized bamboo booster (available at sustainable hemp products)

for an older bub - lay inside the prefold, a medium or large sized bamboo booster, or if that is not enough, use two prefolds.

you will get most absorption, out of bamboo prefolds/trifolds/foldups (compared to the cotton ones).

using a lanolised wool cover over the prefold, will make it last longer than if you put a PUL cover over the top.

as your ticker says you're pregnant, have you seen the Introduction to Cloth packs? they're at the ceejaynappies website. $60 for 6 fitted nappies, 6 boosters, woolly soaker, plus wipes, easily worth ALOT more than $60, i really recommend you go take a look if you're about to have a bub and hacen't used MCN before, trust me, this is a TRUE bargain!!

SHellBell - was it you who said you liked bamboo velour very much? it's lovely as a topper on mama pads too, as soon as you use one of those, it makes you realise how nice it is for your baby to have lovely soft fabric against THEIR skin too.
