What is "Developmental Screening"?

Like a yardstick for measuring height, developmental screening is a tool that helps families measure their children's development through the early years, including:

  1. How children use their hands, bodies, and senses (motor skills).
  2. How children think and solve problems (cognitive skills).
  3. How children use language - speaking, listening and understanding (communication skills).
  4. How children express their emotions and relate to others (social and emotional skills).
  5. How children help take care of their own needs, like feeding and dressing (personal).

Why is developmental screening important?

Developmental Screening is important for all young children! We know that children grow and learn at their own rates, but it's still important to assure that they are developing as expected. You can both track and promote your child's development with fast and fun screening activities that help you:

  1. Make sure your kid is on track
  2. Learn about what's coming next in your child's development
  3. Discover new ways to help your child grow and learn

Screening your child regularly is also the best way to catch any concerns early when the right information at the right time makes all the difference!
