So here are our needs: neither one of us has patience to fuss much with a diaper (and if I expect to keep hubby on board, we need to keep this simple!) so a simple, easy to use system is needed. The less mess we come in contact with, the more my husband will stick with it. My son is very active, so I prefer slimmer, less bulky designs. As to baby "output", current son is a "super soaker". He is also an adventurous eater (current faves are curry couscous salad, diced tomato and avocado with basil and oregano, and sushi - with our pediatrician's blessings). What goes in is an adventure, and what comes out is too. We don't really have diarrhea problems, but there's no telling what consistency or quantities will be and I'm not going to restrict my son's diet just to make diapering easier for me. I'm not a fan of poo duty, but I'll deal! #2 will be exclusively breast fed until starting solids. As to build, boy #1 is a peanut. He started 5lbs, 13 oz (3 weeks early). At almost 16 months he is 31" and 19 lbs. He is muscly and thin. Our ped says based on mine and hubby's build, skinny kids seem to be what's normal and expected for our family (hubby is tall, I'm short, so we'll see what happens height wise. Right now he's not looking like star of the basketball team!). Given that, #2 will probably be skinny too, though he may surprise us. And given past history and the fact that he has a single umbilical artery, I'm guessing he'll start off a peanut, as well.
Our other dilemma: how do you guys handle dirty diaper storage? Keeping stink down is a huge concern for us. We have a diaper genie 2 elite for disposables and it still stinks to high heaven every time you open it and mild to moderately when closed. That's one of the final pushes to switch to cd (we opted for disposables due to odor control and convenience. They don't seem really any more convenient than a good cd system and if I have to smell diapers anyway, disposables have totally lost their edge with us). And any laundering tips or anything else you guys come up with is great too.
