About early child development
A child's early years are very important for healthy development. This is a time when a child's brain and body develop at a rapid pace. Healthy babies and toddlers are more likely to stay healthy through their childhood, teen and adult years.
Ontario offers early child development programs to support children in their growth and development before birth to the time they enter school.
The programs provide services based on your child's needs.
You do not need a referral from a doctor.
