Understanding Your Child’s Development

Welcome to the world of parenting! Your child will go through many changes in just a couple of years. Your child’s development will follow a pattern. As babies grow, they’re able to do more—recognize people, hold things, sit up, crawl, stand and eventually walk. As they become a toddler, they will have constant energy and strong feelings. They will also start to question everything around them. Learning about your child at this age will help you to understand their development. Read more about what your child’s going through in this stage of development.

To help your child understand and cope with feelings you can:

  • describe to them what you think they’re feeling and show that you understand how they feel
  • distract them with an interesting toy, game or song
  • re-direct their attention by changing the activity or move it to a more suitable place




  • Grows quickly (remember that every child grows and develops at their own pace).


  • Learns about love and trust through touching and holding.

What Your Child Needs Your Help to Learn

In these early years, your child will need your help to understand their emotions and their bodies. Here are a few ways to do this:

  • Teach your child that their body is private.
  • Use the correct names for body parts including genitals and reproductive organs: penis, testicles, scrotum, anus, vulva, labia, vagina, clitoris, uterus and ovaries. Knowing the correct names for body parts promotes positive body image, self-confidence, and parent-child communication. It also gives children the language they need to tell a trusted adult if sexual abuse has happened.
  • Make sure your child is able to play with other children their own age often. Your child might not get along with others right away—they’ll learn this with time, practice and the help of you and others. Being able to play with other children will help them to form healthy relationships as they grow older.
  • Help your child understand how gender can be expressed differently. A person’s gender identity may be the same as or different than the sex they were assigned at birth.
