I'd suggest experimenting to find what you like with your 1 y.o. A good way to try something out for a lot less is to buy used
diaperswapper.com. Also, a lot of people really like a stack of prefolds for a newborn.
Anyway.....
What are your favorite AIO's?... Not a fan of AIO's because we like to line dry and they take too long to dry.
What are your favorite pocket diapers?... I like the old style fuzzi Bunz, My Precious Baby by April and Diaper Change. Happy Heiny's are fine too.
Do you like the flushable liners? If so what works best for you?.... I only use flushable liners when I'm out and about. We use a diaper sprayer at home so getting rid of poop isn't an issue.
Do you prefer prefolds or fitteds?.... Each have their place, each has pros and cons. they come out even IMHO.
What are the best inserts & doublers?... I prefer microfiber inserts. I like the thirsties in FB but really, they are all comparable. I even use microfiber cloths in a trifold stuffed in pockets and it works great.
I like the fitteds - what are the best (most absorbent) kinds?... All I can say is to avoid Kushies.
What about the covers - which do you prefer?.... Wool is great for over night, fleece is nice and light and easy to care for. Past that, it's all a matter of personal preference. Just make sure you get quality (keep in mind you usually get what you pay for)
What are the least expensive (but really good quality) CDs you know of?... I love this girl's diapers
Owls R here - Over 100 fabric choices to choose from - Diaper Change Pocket Diapers - Diaper Swappers - Cloth Diaper & Parenting Community
Any laundering tips?.... Cold rinse, hot wash, cold rinse. I've tried soap nuts and really like them. Past that, try not to use too much soap and use vinegar in the rinse, hang to dry when you can (helps the planet and helps to maintain fabrics, elastics and colors)
Diaper pails- where do you find the ones for CD'ing?.... I prefer a dry pail. I find it's less oder, easy, and doesn't take extra chemicals, cleaners, soaps or work. Our dry pail is a camping dry bag from Wal Mart, hung on the back of the laundry room door.
Do you have any more advise to add????.... Keep your stash simple. Also, one size may not be the answer for everyone. I'm not a fan of one size, I prefer to buy a complete stash of smalls and mediums (smalls and Med's may be all you need from birth to potty training).
