The first 1001 critical days – promoting your baby’s development

The first 1001 days, from conception to two years old, is considered to be the most important time in a child’s life for development, more so than at any other time in their lives. In fact, by the age of two, a child’s brain is already 80% developed, and has been making around one million new connections every second.

How can I support my child’s development during this time?

The first 1001 days begins from conception, so you can begin supporting your child’s development from the very early stages of pregnancy.

Explore some of the ways you can do so below.
