This is not a dumb question.  I am still struggling with the cloth wipes thing, which is why I have not made the switch yet.  I need to just do it, though. 

I usually start to wash dipes at night.  I usually end up hanging the fitteds for a while after a spin in the dryer, so I like to have the day to hang them.  I especially like it on days where it is nice enough to hang them outside.

I can not remember when DS's poops changed consistency, but I am sure it was before 18 months.  It took me a while to realize that they were more "adult" though because they tended to get mushed in the diaper.

HTH.
