Introduce
The first 1001 days, from conception to a child’s second birthday, are a critical period for development, as they lay the foundation for lifelong health, wellbeing, and learning. During this time, a baby’s brain grows rapidly, shaped by their experiences and interactions with caregivers. Secure relationships, nurturing environments, and responsive care during this phase are essential for building healthy brains, emotional resilience, and strong foundations for the future. What happens in these early days profoundly influences a child’s potential and ability to thrive.
The 1001 Days Matter Movement is a campaign and initiative that emphasises the significance of these first 1001 days. The infographic below highlights the value of investing in the emotional wellbeing of babies during this timeframe:

Reflect
Stop and Reflect: Take some time to reflect on the significance of the first 1001 days and begin to explore how families can be best supported during this time:
– What do you already know about child development during the first 1001 days, and how has this knowledge shaped your interactions with young children and their families?
– How might practitioners effectively support families to ensure children reach their full potential during this period?
