Aptamil formula: Aptamil 1 for 0-6 months, Aptamil 2 for 6-12 months (follow-on milk), and Aptamil 3 for 1-3 years (growing up milk). Each stage is nutritionally designed for a baby's specific developmental period, with features like prebiotics (GOS/FOS), vitamins, minerals (including Vitamin D for immune support and Calcium for bones), and DHA for brain and eye development. The formulas are inspired by breast milk research, providing a high-quality, complete alternative for parents.
