Kate Middleton has released a heartfelt letter ahead of the launch of a new awareness campaign that educates about the ‘critical importance of our early childhood’. Princess Kate wrote, “During our very early childhood, our brains develop at an amazing rate – faster than any other time of our lives. Our experiences, relationships, and surroundings at that young age, shape the rest of our lives. “It is a time where we lay the foundations and building blocks for life. It is when we learn to understand ourselves, understand others and understand the world in which we live.
