As your baby reaches 1 year, it's important they continue to get the nutrients they need to support their rapid development as they learn to walk, talk and interact with others. Between 1 and 2 years, iron is really important for brain development, but feeding your toddler enough can be a challenge, even with a varied diet, as they only have small tummies. As part of a balanced diet, just 2 beakers (300ml) of Cow & Gate growing up milk provides around 50% of your toddler's iron requirements, to support brain development and vitamin D to support healthy bones and teeth.
