Question: what is the difference between stage 1 and stage 2 baby milk?
Answer: Stage 1 formulas are whey dominant just like breast milk which has a whey to casein ratio of about 60:40. This formula is suitable for babies up to one year old, and is easy to digest. Stage 2 formulas are similar to Stage 1 formulas but with a higher casein to whey ratio of 80:20.
