Developmental delays can affect a child’s physical development, as well as their social and emotional development, communication skills, and learning abilities. As you watch your child grow and anticipate milestones, it’s natural to wonder (and even worry about) whether their development is on track. Chances are that they’ll develop just fine, on their own timeline. But if your child does have a delay, you’ll want to catch it early so they can get a diagnosis and begin treatment.

Children develop at different rates, but most follow a general timeline. Most of the time, babies reach each developmental milestone (like rolling over, sitting, walking, and talking) right around the expected age, and if not, they catch up soon. If your child doesn’t seem to be meeting milestones within several weeks of the average, ask their doctor about it.
Keep in mind that if your child was born prematurely, they might sometimes need a bit more time than other kids their age to reach the various developmental stages. Doctors may track a premature baby’s development using their due date rather than their actual birth date until age 2 or 3.
As a general rule, trust your instincts. If something seems odd or wrong to you about the way your baby or child moves or acts, ask about it. After all, you know your little one best.

What does “developmental delay” mean?
Doctors use this term when a child doesn’t reach developmental milestones within the broad range of what’s considered normal. The delay might be in one or more areas: Gross motor skills such as sitting up and fine motor skills such as grasping and manipulating objects, communication and language skills (both understanding language and speaking), self-help skills (like toilet training and dressing), and social skills (such as making eye contact and playing with others).
What are the chances that my child has a developmental delay?
Various studies have reported that 10 to 15 percent of children under the age of 3 had a developmental delay, such as difficulty learning, communicating, playing, or performing physical activities or practical skills.
Early intervention can make a huge difference for many children with developmental delays, yet one study found that only about 3 percent of kids were getting appropriate attention. That’s why it’s important for you to speak up if you suspect your child has a developmental delay.
Some delays disappear by the time a child heads to school, while other problems won’t be identified until later. About 14 percent of children under the age of 17 have issues such as speech and language impairments, an intellectual disability, learning disabilities, or emotional and behavioral problems.
Among children with developmental delays, about 40 percent have more than one developmental issue, and less than 2 percent have three or more.
If my child does have a delay, what could be causing it?
Sometimes delayed development has a medical cause, such as complications of a premature birth or a genetic condition like Down syndrome. Or it could be the result of a serious illness or accident.
Speech and language delay might stem from a hearing impairment or a problem with the larynx, throat, or nasal or oral cavity. Difficulties with communication might be related to a problem with the central nervous system.
Most often, though, no specific medical cause can be found to explain developmental delays.
Will my child’s doctor check for developmental delays?
Yes, they should. The American Academy of Pediatrics recommends that babies and children be informally screened during visits for any potential delays and be given a formal, structured developmental screening at 9, 18, and 24 or 30 months. Plus, screenings can be done whenever a parent or provider has a concern.
The paediatrician also recommends that children be screened for autism at 18 and 24 months.
Your child’s doctor should ask you about any concerns you have. Using standard developmental assessment tests, the doctor will look for specific motor skills, communication and language skills, and cognitive ability.
If they find anything of concern, they may do a more detailed test or refer you to a specialist in developmental issues. Your child will then have a developmental evaluation, which is a more in-depth assessment of their skills. Or, if your child seems to have a language or communication delay, the doctor may send them to a speech pathologist for an evaluation.
Vision and hearing problems – which may affect development in other areas – can be hard to spot unless you’re a professional. Eye and ear checkups should also be part of every checkup for your child, beginning with their first doctor visits as a newborn. If your child’s doctor suspects a problem, they may recommend more thorough hearing or vision tests.
If you’re worried about your child’s development between regular well-child visits, don’t wait until the next one. Call the doctor and explain your concern. They may be able to calm your fears quickly, or they may want to schedule an appointment for a developmental screening right away.
If your child has been evaluated by their doctor and you’re still concerned, don’t hesitate to get another opinion. (It’s a good idea to keep your child’s primary care provider informed about visits to other doctors and their findings.)
Look for a specialist in developmental issues, or consult a speech pathologist if you’re concerned about your child’s language delay. In addition, most communities have early intervention programs that provide free developmental evaluations and screenings to those who qualify.
