Every child grows at their own pace; however, development has certain milestones. A significant delay at these stages, when noticed early, greatly increases the chances of effective intervention. This is because the period when the brain learns fastest is during the first years; early support means lasting gains.

Areas of Development

Development is monitored across four main areas: gross motor (sitting, walking), fine motor (grasping, finger skills), language/speech, and social-emotional skills. A delay in one area can occur on its own or can involve more than one area.

Warning Signs by Age

Evaluation is recommended in the following situations:

  • 2 months: No response to sounds, no eye contact
  • 6 months: Unable to sit with support, no smiling or turning toward sounds
  • 12 months: Unable to sit without support, unable to make syllables like "mama-dada," no pointing, no response to their name
  • 18 months: Unable to walk, unable to say a single word
  • 2 years: Unable to combine two words, unable to understand simple commands
  • At any age: Loss of a previously acquired skill (regression) — this requires urgent evaluation

Avoiding eye contact, not looking when called by name, repetitive movements, and a marked reduction in social interaction are signs that should be watched for early on with regard to the autism spectrum.

To Catch It Early: Well-Child Monitoring

The most reliable way to detect developmental delay is through regular well-child check-ups. During these check-ups, standardized developmental screening tests are applied, and hearing and vision are assessed. Since hearing loss is a common and treatable cause of speech delay, newborn hearing screening and subsequent check-ups are important.

Advice for Families

Find a balance between worrying and taking action: instead of waiting and saying "it will resolve on its own," ask for an evaluation — most of the time everything turns out to be fine, and if there is a problem, it can be addressed early. Talking a lot with your child, reading books, limiting screen time (especially under the age of 2), and interacting through play all support development.
