Developmental Milestones: What to Expect

Every child grows at their own pace, but there are general communication milestones to help you understand what’s typical at different ages. If your child is developing differently, it doesn’t necessarily mean there’s a problem - but it might be a good idea to explore supportive services. For more information, visit ASHA’s communication milestones.

Self-Check Quiz for Parents

If you’re unsure whether your child might benefit from speech therapy, take this quick self-check:

  1. Does your child have fewer words than expected for their age?

  2. Is your child frustrated when trying to communicate?

  3. Does your child repeat long phrases or scripts but use fewer spontaneous words?

  4. Does your child have difficulty following directions or understanding language?

  5. Do unfamiliar people often have trouble understanding your child’s speech?

  6. Has your child stopped using words or lost language skills they once had?

  7. Are you feeling unsure or concerned about your child’s communication development?

If you answered “yes” to one or more of these questions, it may be helpful to schedule a consultation. Early support can make a big difference, and we’re here to guide you every step of the way.
