I wasn't very involved in my step-daughter's diapering years, but my husband and i have been trying for a baby a LOOOONG time now and we're also looking into adoption - so either way i'm so excited to be a future cloth diapering mom!!
I've done TONS of research and talked to many moms (and dads) on either side. Through it all, i've realized that cloth diapers are by far the best path for me and my family!
The biggest downside i've heard about GDiapers is that they don't seem to save you too much more money that disposables. Cloth is BY FAR the least expensive, even factoring in everything involved (washing, etc). For some people money isn't a huge factor, but for us it really is!
Environmentally, they are all surprisingly quite close on their impact! But if you look at the whole process from production to disposal, cloth diapers still come out way ahead! even though, as many people will tell you, it's not completely benign (but what is these days?). The production of disposables involved a lot of chemicals and natural resource use. And resources & chemicals used to produce and wash cloth diapers is, in my eyes, still better than leaving disposables in landfills with feces and urine in them (which in all reality you're still supposed to dump the disposable diaper contents in the toilet before you toss them out - but who does that?)
And in my eyes one of the biggest benefits is comfort and health of your baby! I can't imagine walking around in plastic underware all day. I'd chose cloth every time! So why not for our babies too? The most common comment i get to that is "disposables absorb the urine instead of making the baby sit in it! that can't be comfortable!" and that's when i say diaper rash isn't comfortable either and that's almost exclusively a disposable diaper problem - from the chemicals and from leaving the diaper on too long because the baby doesn't feel the wetness! plus, cloth babies have a bigger incentive to potty train much earlier because of that very reason!
Ease of use, i've talked to enough women who tell me emphatically that it's nowhere near as gross and difficult as most people think!! Most of them say it's no different that changing a disposable! plus things have come a long way since i was in diapers!
I know some say i'll change my tune when i'm actually doing it, but i highly doubt it. I am so excited about cloth diapering (and amazingly so is my husband!!!)
