A quarter of parents worry about their children’s delayed developmental milestones

As their infants and toddlers grow, many parents may wonder if their children are walking, talking and socializing when they're supposed to be.

In fact, nearly a quarter of parents have suspected their child might be delayed in their development, a new national poll finds – but they may not always share these concerns with a doctor.

Among parents who worried that their child was behind in hitting milestones, nearly one in five did not seek advice from a healthcare or childcare provider, according to the University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health.

Parents may be unsure whether their child is progressing appropriately for their age and are on track with peers. While most do seek a professional's advice, some parents may turn to potentially less reliable sources, like friends or online content."

The majority of parents felt confident in knowing when children should achieve most of their developmental milestones, according to the nationally-representative report based on responses from 779 parents with at least one child five or under.

And more than 80% of those who suspected their child was behind asked for advice from either healthcare providers (63%) or childcare providers (24%).

Still, another 18% only looked up information online, asked family or friends or sought advice on social media. Parents who have worried their child might be delayed are also more likely to learn about milestones from the internet than parents who haven't had these concerns.

"When parents seek advice from friends, family or social media, they may hear inaccurate or outdated information about what's expected during different stages of development," Freed says.

One in three parents also said they've compared their children to a friend's child and a similar number said they compared siblings. Dads were more likely than moms to have compared their child to friends' children (41% vs 28%) or to other children in their family (32% vs. 25%.)

Freed notes that while most milestones typically take place during predictable windows, there's a range of normal for gaining certain skills like walking, talking or laughing.

"It's important for parents to keep in mind that child development is a process that unfolds over time. Each child is unique," he says. "Some children might reach certain milestones earlier or later than same-age peers. This doesn't necessarily mean that one child is advanced or that another is delayed."

Sometimes parents aren't the first to notice potential developmental concerns in their child, according to the poll, with some hearing about it from family members (9%), healthcare providers (9%) or friends (4%).

But if parents have any questions about a child's physical, social/emotional, communication, and cognitive skills, they should ask an expert, Freed says. Healthcare providers will check on a child's progress during well-child visits asking about such developments as rolling over, smiling at a parent, babbling or responding to facial expressions.

For some children, such as those born premature, expectations about the timing of developmental milestones will also need to be adjusted, Freed notes.

"Checking and monitoring developmental milestones can be helpful in detecting delays or problems early and assessing whether children need additional support," Freed says.

"For many parents, well child visits are the best time to discuss age appropriate milestones and to learn what to be looking for by the next checkup."
