Compare Formula Stages by Age
Stage names help organize products, but they are not a ranking and are not identical across brands or markets. Use the minimum age and feeding directions printed on the specific product label.
PRE products can be suitable from birth when the label says so. Ingredients vary by product, and a PRE designation alone does not establish similarity to human milk or improved tolerance.
Shop Stage PRE →Stage 1 products can also be suitable from birth. Composition varies, so do not assume every Stage 1 formula contains starch or changes satiety compared with PRE.
Shop Stage 1 →Stage 2 is intended for use only after 6 months and as part of a diversified diet. Follow the product label and your pediatrician’s advice rather than advancing because a baby seems hungry.
Shop Stage 2 →Stage 3 is not standardized to one age across the catalog. Some products begin at 10 months and others at 12 months, so use the current label for the item you select.
Shop Stage 3 →Stage 4 products are later-stage milk drinks for children who meet the stated minimum age. They should not be used earlier or treated as interchangeable with infant formula.
Shop Stage 4 →Both may be suitable from birth when the individual label says so. Stage names alone do not establish relative safety, similarity to human milk, digestibility, or satiety. Compare the specific labels and ask your pediatrician when feeding or growth concerns are present.

Can I switch stages before the recommended age?
No. Do not use a product before the minimum age stated on its label. Hunger or apparent readiness is not a reason to advance early; discuss persistent feeding or growth concerns with your pediatrician.
Do all brands use the same stages?
No. Stage names, minimum ages, composition, and available product lines vary by brand and market. Check the current label and product page for each item rather than assuming that the same stage number means the same formulation.
Can I mix stages or brands in one bottle?
Do not combine different powders or alter scoop-to-water ratios. Each formula must be prepared exactly according to its own current label. If a transition is needed, ask your pediatrician or follow the manufacturer’s product-specific guidance.
HiPP HA contains partially hydrolyzed protein and is not a treatment for diagnosed cow’s milk protein allergy. Comfort and Anti-Reflux are specialty formulas that should be used after consulting a pediatrician.
