Strangely enough, sometimes it is even harder to tell when to change a cloth diaper when your baby has pooped. Disposable diapers give off a serious nasty odor once the poop hits the diaper. Most cloth diapers, unless they have a detergent or mineral build-up (and in this case they need to be stripped), won’t have as strong of an odor. Additionally, many cloth diapers have such effective elastic around the legs and waist that they keep odor from escaping. I’ve been surprised a number of times when changing my baby, thinking they are only wet, and discovered a surprise poop! You would think the smell would be a dead giveaway but that isn’t always the case.
