As soon as your child is born their health and development become your paramount concern. Scores of family and friends may start asking if your little one is rolling over, crawling, walking or talking. It’s important not to get pulled into comparing your child’s progress with others, but it’s also important to educate yourself on what the childhood developmental milestones are so you can recognize if your child might need early intervention services.
Milestones defined
Vicki Iannotti, M.D., Chappaqua Pediatrics, a division of Boston Children’s Health Physicians, LLP, says there are volumes of material written on children’s developmental milestones, as it is the cornerstone of what pediatricians do for children. “Currently, one in six children in the U.S. has a developmental disability,” says Iannotti. “It is the stance of the American Academy of Pediatrics (AAP) that general pediatricians take a more active role in the evaluation and diagnosis of developmental delays than in the past.”
At birth, pediatricians assess the newborn through a physical exam. Those results, and the newborn’s prenatal history, age of gestation, maternal health, and delivery give the initial picture of the newborn’s development. “There are five streams of development that when typical, occur in an orderly, timed, sequential pattern, affecting each other in a predictable manner,” explains Iannotti. The five streams of development are gross motor, fine motor, language, visual-motor problem solving, and social skills. See the side bar for specific examples of childhood developmental milestones.
Other tools
The AAP recommends the use of a formal questionnaire, “Ages and Stages”, to assess development in each of the five areas at 2 months, 4 months, 6 months, 9 months, 12 months, 18 months, 24 months, 30 months, 36 months, 48 months, and 60 months of age. “The questionnaire is completed by the child’s parents, as they know their child best, it identifies strengths and any areas of potential concern to monitor,” says Iannotti.
In addition, Iannotti says, at well-child visits pediatricians use the Modified Checklist for Autism in Toddlers (M-CHAT), a validated developmental screening tool for toddlers between 16 and 30 months of age. It is designed to identify children who may benefit from further evaluation.
When to be concerned
Parents should be concerned when their child’s development in any area is not made over one to three months of the expected time frame, or if development regresses.
“If a child has a delay of six months or more in meeting milestones in one or more areas of development, it is significant and should be evaluated further,” says Iannotti. Evaluation can include medical genetics, pediatric specialists including neurology and developmental pediatrics, ENT, and or audiology to name a few.
Iannotti says if parents are concerned they should schedule an appointment with their pediatrician to initiate an evaluation. “They should not wait until a scheduled well-care visit,” she advises.
The importance of early intervention
The good news is many developmental delays can be positively addressed. “Evaluating developmental delays, determining a diagnosis, and establishing a treatment plan usually involves specialists in neurodevelopmental pediatrics, physiatry, and a therapeutic team of specialists and educators who provide the necessary interventions over a period of months to years,” says Iannotti.
Keep in mind that from infancy to age 3, your child can receive help through early intervention services. The Individuals with Disabilities Act, a federal law, requires states to provide early intervention. You can request a free evaluation from your state’s early intervention service program. If your child qualifies services may be provided to your child at no cost. A team of educators will develop an Individualized Family Service Plan for your child.
The evidence for early intervention (EI) is irrefutable, says Iannotti. EI programs support parent-child interactions, provide parental education on child development, reduce parental stress and guide parents to become strong advocates for their children.
“Neurocognitive research has shown that there are optimal periods of brain development, more recently termed “sensitive periods”, during which learning is most efficient and almost critical to future success,” says Iannotti. Intervention during these early, sensitive periods of development can maximize the child’s functional potential and further minimize the secondary behavioral, social, and emotional problems that often stem from developmental delays that are not addressed until school age.
In short, EI and targeted therapy has proven to be of tremendous value.
What can parents do to help their baby reach their milestones? “Parents provide the nurturing environment that facilitates brain development, feelings of security and stability to promote emotional well-being,” says Iannotti. “Reading, talking, singing, playing on the floor, supporting motor development through playful situations, and teaching through experiences has immeasurable benefit to the developing infant and child.”
