RE: Would you choose leaks & blowouts or rashes?
Well, I must say that the usual effect of less rash in CDs than in sposies was unfortunately not the case in our household, either. DS is a rashy guy. It took me a long time and a lot of different variables before I finally got the rash under control. BUT we DID get it under control, and I almost never use the sposies.
Diaper rash creme is an important preventative for us. Do you use it much? I experimented and the best stuff for us is Triple Paste, followed closely by Burt's Bees and Boudreaux's Butt Paste. (the butt paste might stain, though, so keep that in mind). Every kid is different so you may have to experiment, too. I know Aquaphor works really well for a lot of babies.
Do you use a wool or fleece cover at night and for naps? That's a must for DS to keep the rash at bay. It lets his bum "breathe".
I also tried a couple different things when washing the diapers. I've found that a little vinegar in a downy ball (so it releases into the rinse cycle) is very helpful, and I do one more rinse after that. Also, the best detergent I've found is Bi-O-Kleen. It's all natural, and doesn't irritate DS's skin. A little bit goes a long way.
Some naked-butt time daily is very helpful. My ped tells me that the only kids who never get diaper rash are kids who don't wear diapers.
All that said, I know that many parents have found that using sposies at night and for naps is what works best for them. That's OK too! If the leaks are a big problem with that solution, though, I'd suggest moving up a size and then maybe putting a cover over the sposie.
