“During our earliest interactions, relationships and experiences, with those who love us, even before we are born, we lay the foundation for so much on which that future will depend.

'But only by valuing and supporting the vital role of adults in a child's world can we hope to make a difference.

“And so tonight's guests are invited in recognition of their support of our youngest children as we shine a spotlight on the vital role they play in nurturing and educating the future generation.
