Why do you have different stages 0-6 months/ 6-12 months:

In Australia we have specific standards & nutritional requirements for our infant nutrition for each stage & stage of development

These age brackets follow the stringent infant nutrition guidelines set by FSANZ (the food safety guidelines we follow in Australia), as 0-6 month old babies, have different nutrient requirements for 6-12 months babies). These age specific nutrition guidelines were made to more closely approximate breast milk nutrients which evolve as babies age.
