Developmental Milestones

The first three years of life are a time of rapid growth and development. Although children develop at different rates, the majority of children meet developmental milestones or sets of skills within a certain age range (Berk, 2006). For example, most young children will sit alone between 5 and 9 months of age and begin to walk between 9 and 17 months of age (Berk, 2006). If a child has not walked by 18 months of age the child is experiencing a developmental delay.

Developmental Delay

A child is considered to have a developmental delay if they do not meet developmental milestones in one or more areas of cognitive, physical, communication, social, emotional or adaptive development (IDEA, Part C 632 5Ai) within a typical period of time. Developmental delays are generally an early warning sign that the child needs further observation and possibly a professional assessment. Discuss concerns with a health professional.

Most young children (under the age of 3 years) with developmental delays benefit from early intervention services. Therefore, it is important to recognize the early warning signs of possible delays. The following lists gives some early warning signs in the areas of large motor, fine motor, cognitive and communication, socialemotional, behavioral, hearing and visual development. This is not an all inclusive list but gives some common indicators.

  • Only walking on toes, not the soles of feet at age 2

Physial Concerns (fine motor)

  • Uses a fisted position with both hands after 6 months of age
  • Unable to clap hands by 12 months
  • Does not reach or point by 12 months
  • Unable to use a mature pincer grasp (thumb to index finger) by 18 months

Social-emotional Concerns

  • Does not show enjoyment or affection to caregivers by 7 months of age
  • Does not imitate adults

Behavioral Concerns

  • Very sensitive to sound and/or touch
  • Self-stimulating behavior such as rocking the body or hand flapping
  • Aggressive or violent behavior on a daily basis

Visual Concerns

  • Rubs eyes frequently
  • Unable to follow objects or people with eyes by 3 months
  • After 6 months has difficulty making eye contact, eyes appear crossed, or turned in or out all of the time
  • Eyes appear abnormal in size or coloring

Hearing Concerns

  • Has frequent earaches
  • Does not appear to hear loud noises
  • Turns body so the same side is always turned toward the sound
  • Fails to develop sounds or words at appropriate age

Identifying Developmental Delays

Developmental delays are identified through playbased assessments. Usually a child goes through a development screening first to identify whether further evaluation is needed. If the screening suggests a developmental delay, a longer, in-depth developmental evaluation is conducted by a trained professional. Assessments include identifying the strengths and needs of the infant or toddler and determining appropriate services. A family-directed assessment is also conducted, and if services are needed a team of professionals creates an Individualized Family Service Plan (IFSP) which includes a variety of early intervention services (IDEA, Part C Section 636).

Early Intervention Services

Early intervention services can help a child with developmental delays progress in meeting developmental milestones. Nevada’s Early Intervention Services (NEIS) help to identify infants and toddlers who are at risk or who have developmental delays. NEIS offers many different services, such as physical and speech therapy.
