Understanding Developmental Milestones

At Building Blocks Childcare, we use the CDC’s developmental checklists to help monitor your child’s growth and progress. These guidelines support us in understanding typical developmental stages across early childhood. Every child develops at their own pace, and milestones may be reached at different times. For this reason, we use these checklists as flexible tools rather than strict requirements. Our focus is on supporting each child’s individual learning journey, meeting them where they are, and encouraging growth through developmentally appropriate experiences.

Centers for Disease Control and Prevention (CDC) developmental milestones are age-based skills and behaviors that most children reach as they grow. These milestones cover how children:

Play and learn
Speak and communicate
Move physically
Interact socially and emotionally

The CDC’s “Learn the Signs. Act Early.” program provides milestone checklists from 2 months through 5 years old. The current milestone ages are:

2 months, 4 months, 6 months, 9 months
1 year, 15 months, 18 months
2 years, 30 months
3 years, 4 years, 5 years

The CDC updated its milestone checklists in 2022 to focus on milestones that at least 75% of children can do by a given age, helping identify possible developmental delays earlier.

Examples include:

By 6 months: laughing, rolling over, reaching for toys
By 1 year: waving “bye-bye,” pulling to stand
By 2 years: using 2-word phrases, kicking a ball
By 4 years: telling simple stories, catching a bounced ball

The CDC emphasizes that milestones are guidelines, not rigid rules. Children develop at different rates, but missing multiple milestones or losing skills can signal the need for developmental screening.

Why Early Intervention Matters

The early years of a child’s life are an incredibly important time for growth and development. From birth to age three, children are building the foundations for communication, movement, learning, relationships, and emotional well-being.

Sometimes families have questions or concerns about their child’s development, and Early Intervention Colorado is there to provide support, guidance, and reassurance. The goal is not to label a child, but to better understand their unique strengths and gently support areas where they may need additional help.

Early intervention services are designed to fit naturally into everyday life. Support happens through play, routines, and daily interactions, helping learning feel comfortable, meaningful, and achievable for both children and families.

Receiving support early can make a lasting difference in a child’s development while also giving families greater confidence and peace of mind. It’s about building skills early in a way that feels caring, respectful, and encouraging.

If concerns ever arise, Early Intervention can be a supportive place to turn for guidance, resources, and next steps.
