S.,
I may be a lazy mom, but I could not imagine having to wash so many washcloths! Especially with so much else to worry about with a new baby and getting into a routine. Yikes! We've always used wipies; we used the sensitive skin Pampers wipes for the first couple of months and then used to cheapies from Sams Club or Walmart after that.
I've also always used powder (Johnson's pure cornstarch) and even just regular corn starch (yep, the stuff you cook with) in my girls' diapers. I shake some in every diaper change. They've very rarely had any diaper rash...only when I've been slow to catch poopie pants right away or when my eldest had too much citrus. Only on the few occasions they've had a rash do we use the cream stuff.
Unlike a previous poster, I had to change every time they woke. My youngest hated having pee pee pants and wouldn't go back to sleep if they were the slightest bit wet.
Good luck to you! Wishes for a smooth quick labor.
