THE REFERENCE SHELF
Purchase math
Formula unit prices: dry ounces are not fluid ounces
Compare powder with powder using net weight, and liquid with liquid using the same volume unit. Never treat a dry ounce as a fluid ounce or use package-price arithmetic to select a medical category.
Baby-food jars vs pouches: compare equivalent contents and quantities
Compare the intended product, ingredients, texture and declared net weight before choosing by container style. A pouch count and a jar count are not comparable until you know how much each contains.
Baby-snack value: compare net weight, not a serving promise
Compare actual net weight and the intended product, then evaluate the label and eating guidance separately. A package’s serving count is not an individual feeding recommendation.
Three powder-formula listings: dated prices and net-weight arithmetic
These three official US listings illustrate purchase arithmetic, not a nutritional ranking or a recommendation to switch products. Prices were observed November 4, 2026; final checkout and recall checks remain separate.
