administration (fda) guidelines. as reported by the mayo clinic: “as with most consumer products, brand-name infant formulas cost more than generic brands. but that doesn't mean that brand-name formulas are better. although manufacturers may vary somewhat in their formula recipes, the fda requires that all formulas contain the same nutrient density.” similarly, in canada all infant formulas regardless of brand are required to meet standards set by health canada. follow-on and toddler formulas follow-on or toddler formulas are sold for ages 6 months to 3 years (when infants are typically breastfed). in the us, a transition formula is marketed for children from age 9 to 24 months, and a toddler milk is sold for children age 12 to 26 months. in both cases, the ingredients are powdered milk, corn syrup and other added sugars, vegetable oil, and salt. toddler formulas are not nutritionally complete, nor are they subject to the same regulations or food labeling laws as infant formula. critics have argued that follow-on and toddler formulas were introduced to circumvent the regulations regarding infant formula and have resulted in confusing advertising. an early example of follow-on formula was introduced by wyeth in the philippines in 1987, following the introduction in this country of regulations on infant formula advertising, but which did not address follow-on formulas (products that did not exist at the time of their drafting). similarly, while infant formula advertising is illegal in the united kingdom, follow-on formula advertising is legal, and the similar packaging and market results in follow-on advertisements frequently being interpreted as advertisements for formula.
