Yes, I am - in fact, I'm cloth diapering Eva full-time with no disposables.
During the day, I'll change her every 3-4 hours (sometimes more frequently if she's had a lot to drink and such). I do my CD laundry every two days as per recommendation coz if you wait any longer, it'll stink. I'll rinse out the pee first and then dump in the washing machine for another prerinse before the actual full cycle wash coz I'm a stickler for keeping my CDs smelling clean. :P
As such, my CDs are washed separately from my regular laundry. No issues there with electricity or water bill.
For night time, I use another brand of CDs - Happy Heinys - with a bamboo insert and a microfiber doubler. This will go on her at 1130pm and come off her at 530-6am. Before that, she gets a regular day diaper at 7pm but sometimes there is no pee in it so we use it again at around 9am. In between, she has a BumGenius diaper with an insert and doubler because she tends to pee most upon waking up in the morning as compared to nap times during the day.
If you're planning on using Bumwear at night, you can try to use 3 inserts OR get bamboo/hemp inserts as they are more absorbant.
So far, my experience with Bumwear has been very positive. It can last four hours with two inserts and even then, it's not very heavy (meaning it can hold more pee) and more importantly, no leaks!
