Question: when switching from formula to whole milk?
Answer: For example, you can start the transition by giving her 6 ounces of formula with 2 ounces of whole milk. Next, shift the ratio to 4 ounces of formula with 4 ounces of whole milk, and then to 2 ounces of formula with 6 ounces of whole milk. Finally, you can offer her pure whole milk.
