Children develop at different rates, with skills emerging at advanced rates, normal rates, or below age expectation. Often, parents gage a child’s progress by comparing him to other children his age or reflecting on how older siblings developed. Developmental delays can go unrecognized and untreated until a child experiences initial exposure to a structured group play environment, such as mommy and me classes, day care centers, baby gym centers, and pre-school programs.
During a routine check-up, your child’s pediatrician will do a general developmental overview, asking you about what milestones your child is achieving, but this is usually a brief question-and-answer between parent and physician. Typically, your doctor has an overflowing schedule that hinders her ability to thoroughly address your child’s progress through each of the five developmental domains (Cognition, Communication, Socialization, Motor Skills, Adaptive Behavior skills). As the parent, you are the constant observer and the best advocate for your child.
From the moment your child is born, his progression through each of the five developmental domains begins. One might ask, but how can an infant communicate? What motor skills would one expect for a child who can’t even walk yet? Assessment tools, such as the Developmental Assessment of Young Children, are used for children from birth to age 5, with other versions addressing the milestones of older children. Developmental milestones focus on what a child can do by a certain age. Red flags can warn parents and caregivers of potential delays and disabilities. So, let’s test your knowledge on what is typical or atypical in child development.
• At what age do children typically put two words together?
Answer: 18 to 24 months
• What is the average attention span for a 3 year old?
Answer: About five minutes
• At what age should children be able to pronounce most speech sounds correctly?
Answer: 5 years old
• What is the average age that a child walks?
Answer: 12 to 18 months
• At what age does a child typically identify primary colors (red, blue, yellow)?
Answer: About 3 years old

Keep in mind that these red flags are guidelines and are not intended to diagnose any disorder or disability, but should serve to cue parents and caregivers to have their child evaluated. Numerous research studies have concluded that developmental issues addressed as early as possible yield the most benefits.
According to the results of The Abecedarian Program headed by Dr. Craig Ramey, the earlier a problem is addressed, the more likely the child will make great improvement. As a child ages, the rate of improvement tends to slow down. Be aware of any loss of skills. Note any recent changes to your child’s life (new sibling, divorce, moving, etc.) and share that information with the professionals involved in your child’s care. The evaluation process can only be authorized by a primary care giver with the process costing you nothing but your time, and patience.
