The Critical Role of Dairy in a Child’s First 1,000 Days

What are the first 1,000 days, and why do they matter?

From pregnancy through toddlerhood, the first 1,000 days are a critical development period for your child. A baby’s brain grows faster than at any other time in life, and nutrition during this time plays a major role in that process.

Dairy Fuels Brain Development

The brain grows fast! A baby’s brain doubles in size in the first year. It triples by age three. And up to 80% of total brain growth happens before your child turns three! Your child needs essential nutrients every day to support this rapid growth. Essential nutrients are nutrients your body needs to grow and function properly, and our body can’t produce enough on its own—requiring us to eat food to get them. Dairy foods like milk, cheese, and yogurt are natural sources of:

  • Vitamin B12 – supports cognitive development and learning
  • Iodine – helps with memory, focus, and neurological function
  • High-quality protein – builds brain cells and tissues
  • Choline – supports brain development  

 

For Pregnant & Breastfeeding Moms: Nourish to Nurture 

Your nutrition during pregnancy directly affects your baby’s brain development. So why is dairy important here? Dairy includes choline and essential nutrients like vitamin B12 and iodine, which support baby’s cognitive development. It also provides protein for healthy maternal weight gain and fetal growth.

Toddlers (1–2 Years): Growth is Still in High Gear 

A child’s brain is still growing fast—even into their toddler years.

  • Up to 80% of brain growth occurs by age 3. 
  • A toddler’s diet plays a key role in maintaining that momentum.

 

Daily dairy delivers: 

  • Milk, cheese, and yogurt provide a reliable source of vitamin B12, iodine, protein, calcium, and more. 
  • Helps balance gut health as toddlers transition to table foods.
