Serve and return describes the back-and-forth exchanges in which a baby sends a signal, such as a babble, look or gesture, and an adult responds with words, a smile or touch. Harvard's Center on the Developing Child describes these interactions as essential for building the architecture of the developing brain.

How do I do it?

The Center on the Developing Child suggests five steps:

  • Notice the serve and share your child's focus of attention
  • Return the serve by supporting and encouraging
  • Give it a name: label what your child is seeing, doing or feeling
  • Take turns and wait for your child to respond
  • Practise endings and beginnings: notice when your child is ready to move on
