Stage 2 formulas by HiPP Germany, Holle, and Lebenswert are intended for babies between 6 and 10 months of age, while the stage 3 versions thereof are intended for 10-12 months. HiPP Dutch and HiPP UK, though, are different in that the stage 2 formulas are intended for 6-12 months and the stage 3 versions thereof (i.e. HiPP Dutch 3 and HiPP UK 3) are intended for 12-24 months. The biggest difference between these 6-12 month formulas and prior stages relates to iron content. Starting at 6 months, babies require more iron than prior to 6 months and for this reason, stage 2 formulas contain more iron than stage 1 and PRE formulas.
