Both our Stage 1 and 2 formula contain no fish oil, soy oil, or palm oil. Stage 2 does have slightly more iron to meet the higher iron demands of an infant once they turn 6 months old.
Usually, parents switch to Stage 2 baby formula when their baby is 6 months old and starting to wean. The general taste should remain the same, however this milk includes more minerals for your baby's higher weight.
Please note that although we know our baby formula inside and out, we are not medical professionals. We always recommend checking in with your GP before transitioning to new baby formula or supplementing breast milk with baby formula. Some health professionals may advise you to stay on Stage 1 for 6-12 months.
