I have a fairly heavy flow... do you guys think I could use these pads without having to change obsessively?
I bet they would work fine. I haven't used cloth pads yet but I cloth diaper my baby and cloth absorbs SOOO muchbetter than disposables. Just make sure that the inners are made of something like hemp jersey, hemp fleece, cotton flannel, burley knit terry, etc. Just make sure it is 100% cotton/hemp, no poly/nylon/etc.
