Diaper close-up: A yellow, creamy liquid, which can look like mustard mixed with cottage cheese. It may also be seedy and have a mild, sweet smell.
When it happens: Breastfeeding
What's going on? Breast milk gives your baby's poop its color, texture, and odor (some moms liken it to pancake batter or buttered popcorn). Breastfed babies tend to produce fewer stinkers than their formula-fed chums.
How to handle: Don't rush to change your baby's diaper the minute you hear an explosion (yep, that's what it can sound like). Many babies have several small poops -- or, rather, squirts -- in succession, so wait a few minutes to be sure yours is done.
