Growth and Development - School-Aged Children 

In a child's life, growth and development is very important for his or her health. Parents, health professionals, educators, and others can work together as partners to help children grow up to reach their full potential.


Is my child growing well?

  • Children come in all sizes and shapes, some may be tall and some may be shorter, some may be lighter and some may be heavier
  • Many things affect a child’s growth and development, such as their eating habits, physical activity, environment and parent’s height.
  • Most children follow a regular growth pattern that is unique to them

How do I track my child’s growth?

The Growth Chart is a type of graph used to track a child’s growth

  • Regular weight and height measurements will show your child’s special pattern over time 

What are milestones?

  • As a child grows, we expect them to learn new things by certain ages

If you have concerns, be sure to talk to your health care provider about your child’s development.  They will help you decide if more testing or assessment is needed.

What is a Nipissing District Developmental Screen?  

  • The Nipissing District Developmental Screen is a parent checklist that is easy to use.
  • It looks at 13 developmental stages between infancy and age 6.
  • Knowing what growth and development stage your child is at, is key to knowing what parenting strategies would be best for your child 
  • To give you an idea about where your baby or child is at in their development, you can complete a Nipissing District Developmental Screen (NDDS) at each developmental stage: 1 & 2 months, 4 months, 6 months, 9 months, 1 year, 15 months, 18 months, 2 years, 30 months, 3 years, 4 years, 5 years, and 6 years. 
  • If you have any concerns about your child’s development, be sure to talk to your health care provider.  They will help you decide if more testing or assessment is needed.

What about sexual changes as my child grows?

  • There are many chances to talk to your child about changes in their body during puberty and you can be the best support for your child during this time in their life.
  • As they grow a bit older, you will also need to talk to them about sex, and we can help you feel more comfortable with this discussion.

Why do I need to get my child’s vision tested?

  • Children with poor vision often have a hard time doing their school work 
    • Sometimes they are thought to have a learning or behavioural problem, even when they don’t
  • Having your child’s vision tested is a key part of getting ready for school
    • Make it a part of their regular back-to-school routine 
  • It is important to find eye problems early so that they can more likely be corrected
  • Your child can have their eyes tested for free up to their 20th birthday.
    • Eye tests are free once a year when you show your child’s health card to an eye doctor
  • Often there are no signs that your child has a vision problem
