Generally I use the terry cloth side for poop and the other sides for pee or light clean up. That system has worked for us for a year, although I do grab a disposable wipe sometimes when I'm feeling lazy, when my solution bottle is empty or when Kai had a disposable diaper on. I honestly feel the longer ones are a bit too long and the Bumkins flannel ones are wider than I'd like. The midsize wipe is perfect but their sizes don't stop me from using them. Another note is that the terry needs to be pretty wet to slide across Kai's skin. When it's not wet enough it doesn't clean as well. I stack all my wipes in a pile next to my solution on our changing table.
As for my solution I use baby wash, coconut oil and water. I have read a large number of wipe solution "recipes" on the Internet that include some kind of oil, different soaps, essential oils and more. When I first made it I just wanted to use products I already had on hand. I don't really measure anything because I'm still trying to find a good amount of each. Generally I put a little soap, a little oil and fill the rest of the bottle with water and shake it up. I have found the products below go well together. Aveno Baby Wash in place of the Johnson and Johnson wash smells awful! I've also tried the lavender scented Target brand wash and that works well. If you don't like the coconut smell, refined coconut oil or baby oil can be used. The bottle I use is a Windex Touch Up bottle. It works phenomenally! I just dumped the cleaner into another bottle and washed it up good and made my solution. (I found the idea from another great cloth diapering momma, but I can't find the blog post now! If anyone knows where it is let me know. I'd love to credit her.)
