  • Developmental Screenings

    You and your child can complete the American Academy of Pediatrics approved Ages and Stages Questionnaire (ASQ). The ASQ looks at your child’s strengths and challenges, educates parents about developmental milestones, and incorporates parents’ expert knowledge about their children to learn more about their development. You can complete an ASQ for FREE online here or pick one up in our lobby. 

  • Community Partners

    The Good To Go From Head To Toe initiative is a community collaborative effort of many partners including American Academy of Pediatrics – California Chapter 4, Children & Families Commission of Orange County, Orange County Department of Education and Kaiser Permanente. The strength of our initiative and ability to reach so many families is solely due to our strong partnerships. Listed below you will find several of our partners

  • What Are Developmental Milestones?

    Developmental milestones are functional skills or age-specific tasks that most children learn or demonstrate in predictable stages of growth.

    How Do They Develop?

    Developmental milestones are like stepping stones, with each milestone building upon the previous to support a child’s growth and development. For example, most children learn to crawl and pull themselves up to a standing position before they learn to walk. A child’s development progresses through four major skill areas:

    • • Movement and muscle
    • • Communication and expression
    • • Play and social
    • • Thinking and problem solving

    In reality, each milestone does not develop in isolation, as development in one area is reinforced and enhanced by growth in others.

  • Every Child is Unique

    This natural progression of growth makes it important to understand every developmental milestone as a way to gauge each new stage of development in your child’s life. Every child develops, learns, and plays at their own pace
