What is child development?
A child’s growth is more than just physical. Children grow, develop, and learn throughout their lives, starting at birth. We can find out about a child’s development by how they play, learn, speak, move, and behave.
What is developmental delay?
Skills such as taking a first step, smiling for the first time, and waving "bye-bye" are called developmental milestones. Children reach milestones in playing, learning, speaking, behaving, and moving (crawling, walking, etc.). A developmental delay happens when your child is slow to reach these milestones.
