Bottle rash

That's what it should be called. The only reason babies or infants get the dreaded "diaper" rash is from bottles of formula that have been prepared and left out for over an hour, or have been reheated and subsequently administered to the unknowing child. For toddlers, it is food that has been opened and is more than 24 hours old. The bacterium that begins to grow in these items is a result of exposure to air and irritates the child's premature digestive tract, causing the ubiquitous "diaper" rash. Bottom line (pun intended): Make what you need, use it right away (or freeze it), and don't be lazy. Think you are doing your kid a favor by creaming his hiney? Guess who's to blame for that horrible, shiney, red-as-a-granny smith apple tush? That's right, you are. Bravo.
