Which description best characterizes stools of formula-fed infants?

• A. Mustard-yellow stools
• B. Stools more solid and pale yellow to light brown
• C. Stools that are green and very loose
• D. Stools that are black and tarry

Answer: (B)

Stool characteristics differentiate feeding types in infancy, and for formula-fed babies the stools are typically more formed and have a pale yellow to light brown color. This comes from the formula’s composition, which often results in stools that are firmer and less loose than those of breastfed infants. The pale yellow to light brown hue reflects the digestion of formula solids with less rapid intestinal movement, producing a stool that's not as runny as breastfed stool. The other descriptions don’t fit the usual pattern for formula-fed infants: mustard-yellow stools are more common with breastfeeding, green and very loose stools can indicate overactivity or a temporary issue rather than the norm for formula, and black and tarry stools suggest bleeding or other concerns rather than routine formula digestion. So the description that matches formula-fed stools best is the more solid consistency with pale yellow to light brown color.
