Milestone Myths You Can Let Go Of

Posted by Ingrid Cruz

Parenting is rewarding and joyful, but it also brings with it a unique set of stressors. Online forums, news stories, and well-intentioned loved ones often dish out advice that may or may not be helpful. It’s no wonder milestone myths continue to persist and strike a chord of fear. 

Researching and vetting information can take some time. That’s why we spoke to Dr. Robin Baweja, a Toronto-based pediatrician who helped us parse through common milestone myths so you don’t have to.

Myth: Girls develop speech faster than boys

In many cultures it’s common to believe that girls will develop faster than boys. Dr. Baweja says that “Boys and girls have the sustainability to reach the same milestones. They may have different temperaments, but there aren’t too many milestones I can think of that a girl has a better or faster chance of reaching faster than a boy can.” 

A study on crawling expectations from the Journal of Experimental Child Psychology explains that boy and girl infants showed relatively no differences in fine motor skills as infants.

Myth: It’s never too early to check for autism/ADHD, etc.

Physical issues and potential infections are of concern to parents, but autism and attention deficit hyperactivity disorder (ADHD) are also issues parents understandably want to screen for. 

They may notice a lack of eye contact within the first few months and start worrying about whether or not they should screen their baby. As it turns out, it can be too early to screen for autism, ADHD, and other forms of neurodiversity in some circumstances. 

“From a development standpoint, the first standardized screening tool we use for autism is at 18 months,” explains Dr. Baweja. “It’s called the M-CHAT. 18 months is usually when parents start to see red flags. But if parents are voicing concerns before the 18 month mark, I definitely try to reassure them because that is probably too early to assess.”

Myth: Your child needs to walk by 12 months

For whatever reason, parents continue to believe their child must walk by 12 months and that progress made after this is “late.” The truth is, only a few children can walk by 12 months. 

Per Dr. Baweja, “Pediatricians expect a child that's 12 months old to be sitting upright, pulling to stand and cruising, but not walking and taking unassisted steps.”

Myth: Children must be toilet-trained by ages 2-3 

This myth may exist because daycares often pressure parents into ensuring their children are toilet-trained before enrolling their child into a program. Toilet-training a child by the age of 2 or 3 may even simplify a parent, babysitter, or caretaker’s routine. 

However, many children may still have issues going to the bathroom at around the ages of 2 and 3. According to Dr. Baweja, “Most bladder and bowel control doesn't actually happen until kids are three. If a child is potty-trained by age four they’re within the normal range. Don't be discouraged if your kid takes a little bit longer. That’s a normal part of development.”

Myth: All of your children will have the same development schedule

Parents of more than one child find it natural to compare their children—especially if they’re twins or other multiples. Dissimilar development is normal in siblings and is nothing to worry about. 

“What’s important”, says Dr. Baweja, “is that children are within age appropriate ranges in their development even if their paths vary.”

Fact: Pediatricians are here to help

That being said, do bring up any concerns or red flags you notice. Pediatricians are there to help you take care of your child and reassure you when there are no problems. They deal with children every day, can provide you with tools, and refer you elsewhere if needed.

Some children may still reach development milestones 2 to 3 months later than established guidelines and still be perfectly healthy, but don’t be afraid to ask questions or bring up concerns.

“18 months is usually a good age to assess real development,” says Dr. Baweja. This is when pediatricians will closely look at walking, coordination, and other abilities. Even so, keep in mind that there may be reasonable explanations for why some children take longer to reach their milestones. 

Common reasons for later development in some children include genetic conditions, Down syndrome, cerebral palsy, or a surgery early in life.


With so much online information it’s important to talk to your doctor if you’re concerned about your child’s health. If you’re going to search for clues online, stick to reputable sources such as the Canadian Paediatric Society or the American Academy of Pediatrics
