Find the Perfect Formula for Your Baby's Stage

Expert guidance on choosing the right organic European formula based on your baby's age and developmental needs

What are formula stages and why do they matter?

European organic formulas are divided into stages based on your baby's age and nutritional requirements. Each stage is carefully formulated to provide the optimal balance of proteins, fats, carbohydrates, vitamins, and minerals for that specific developmental period.

The three main stages are:

  • Stage 1 (0-6 months): Designed for newborns with gentle, easily digestible proteins
  • Stage 2 (6-12 months): Follow-on formula with increased nutrients for active babies
  • Stage 3 (12+ months): Toddler formula to complement solid food introduction
0-6 Months
