Parenting Advice That Changed: 7 Safety Rules Every Parent and Grandparent Should Know

Have you ever heard a grandparent say, "We did it this way, and you turned out fine"?

They're not wrong. They were following the best medical advice available at the time.

In this episode of MomDoc Talk, board-certified pediatrician, author, and mom Dr. Kristen Cook explains why parenting recommendations change over time and how decades of research have dramatically improved child safety.

From babies sleeping on their stomachs to putting rice cereal in bottles, from riding in cars without seat belts to skipping bike helmets, many practices that were once considered normal are no longer recommended because science has taught us better ways to protect children.

Dr. Cook walks parents and grandparents through some of the biggest changes in pediatric medicine, explaining the evidence behind today's recommendations while emphasizing an important message: parenting isn't about perfection. It's about learning, growing, and doing better as new information becomes available.

Whether you're raising young children or supporting grandchildren, this episode will help you understand why modern parenting recommendations continue to evolve—and why that's something worth celebrating.

Welcome to Mom Doc Talk with Dr. Kristen Cook, where real-life parenting meets medical expertise. I'm your host, a pediatrician with over a decade of experience, and just like you, a parent navigating the ups and downs of raising good human beings. With stories from my own experiences of mom, lessons in child development, and insights based on scientific evidence, I'm here to share practical strategies that work. Let's dive into this journey together and make parenting feel a little more peaceful and a lot more rewarding.(Music) Hi everyone, and welcome back to Mom Doc Talk with Dr. Kristen Cook, where we combine science, compassion, and practical parenting advice to help you raise healthy, resilient children. I'm your host, a board-certified pediatrician and a mom of two, and today we're taking a fun, but incredibly important, trip back in time. If you grew up in the 1970s or 1980s, chances are you survived some parenting practices that would make today's pediatricians cringe. Maybe you rode in the back of a station wagon without a seat belt. Maybe you slept on your stomach as a baby. Maybe you biked everywhere without a helmet. And here's the important thing. Our parents weren't bad parents. They were following the best information available at the time. Parenting recommendations are constantly changing because science changes. Medicine evolves. Research improves. The goal of today's episode isn't to criticize previous generations. It's to celebrate how much we have learned. One of my favorite quotes is,"When we know better, we do better." It's a motto that I live by. Today I'm discussing some of the biggest parenting recommendations that have changed over the past several decades, and more importantly, why they have changed. Parents often wonder,"My mom says she did this with me and I turned out fine. Why have things changed?" That's a fair question. Medicine is evidence-based. That means recommendations aren't based on opinions. They're based on large research studies involving thousands, or sometimes millions, of children. Sometimes the recommendation changes because researchers discover something safer. Sometimes technology improves. Sometimes we discover unexpected risks. One example? In the early 1990s, researchers noticed that babies who slept on their backs were much less likely to die from Sudden Infant Death Syndrome, or SIDS. That single discovery has saved thousands of babies' lives. So when grandparents say, "Well, we always did it this way," they're right. They did. But today's recommendations are based on decades of additional research. Perhaps one of the biggest parenting changes involves infant sleep. Throughout the 1960s, 70s, and much of the 80s, parents were often encouraged to place babies on their stomachs to sleep. Why? Doctors believed babies might choke if they spit up while lying on their backs. At the time it sounded logical, but research later proved the opposite. Healthy babies actually protect their own airway remarkably well. That's why they frequently choke on their own saliva. When babies sleep on their backs, their airway anatomy helps prevent aspiration. They can swallow secretions naturally, and they are actually less likely to suffocate. Researchers discovered stomach sleeping dramatically increased the risk of Sudden Infant Death Syndrome. In 1994, the American Academy of Pediatrics launched the famous Back to Sleep campaign, now called Safe to Sleep. Since then, SIDS deaths have declined by more than 50%. Today's recommendations for infants are, always place babies on their back, every nap, every nighttime sleep. Use a firm mattress with tight-fitted sheet. Don't use blankets, pillows, stuffed animals, or crib bumpers. Babies should sleep alone on their own sleep surface, in the parent's room, but not the parent's bed, for at least the first six months of life. I have lived through two babies who despise sleep and fought it at all costs. It was exhausting. But a healthy, alive baby, who sleeps poorly, is much better than a baby who never gets the chance to become an adult because they were placed on their abdomen to sleep. Moving on, if you ask enough grandparents, someone will eventually say,"Just put a little rice cereal in the bottle. They'll sleep all night." This recommendation was incredibly common decades ago. Parents believed a fuller stomach equaled longer sleep. Unfortunately, research simply doesn't support that idea. Adding cereal rarely improves infant sleep. Instead, it increases the risk of choking. Babies aren't developmentally ready to coordinate swallowing thickened liquids. In addition, adding cereal to bottles contributes to overfeeding. Babies may consume more calories than they actually need. Several studies have associated early introduction of solids with increased obesity risk in children. In addition, adding cereal to a bottle can cause digestive issues. Infant digestive systems aren't mature enough before about four to six months. Today's recommendation is that babies only consume breast milk or formula for approximately the first six months. Then introduce spoon-fed solids, not cereal in bottles, when babies demonstrate developmental readiness, including sitting with support, good head control, and interest in food. There are a few exceptions. Certain infants with severe acid reflux or swallowing disorders may require thickened feeds, but only under medical supervision. Do you remember being sick as a kid in the 1980s? It often involved a lot of blankets. How many of us remember hearing,"Bundle up, you need to sweat it out"? This advice was incredibly common. The idea was simple. If you're sick and have a fever, you need to sweat. Then you'll get better. But that's not actually how fevers work. A fever is the result of your body's thermostat intentionally raising your temperature. It's part of your immune response. The increased body temperature helps slow the replication of germs and helps the immune system work better. Sweating happens when your fever begins coming down, not because you forced it to happen. Bundling children in multiple blankets or heavy clothing can actually increase body temperature further, cause significant discomfort, increase the risk of dehydration, and delay cooling. By the way, the reason we sweat is to cool the body down. The concept of sweating it out is actually a complete contradiction. These days, when a child is sick, it is recommended to dress children comfortably, offer fluids frequently, and treat the child, not the number on the thermometer. A playful toddler with a fever of 102 degrees Fahrenheit may not need medication if they're playful and active. Meanwhile, a sleepy or uncomfortable child with a temperature of 100.8 degrees Fahrenheit deserves careful evaluation. Parents should seek medical attention if infants younger than 2 months old have a rectal temperature of 100.4 degrees or higher, children are difficult to wake, they have trouble breathing, they become dehydrated, or they have seizures, severe headache, stiff neck, confusion, or a rash that concerns you. Fever itself is rarely dangerous and in most cases does not warrant a trip to the emergency room. One of the greatest advances in child safety has been improvements in car seats. In the 1970s, many children simply sat on the seat, or even on their parents' lap. Sometimes parents held infants in their lap even if they were driving. This does not protect a child if there is a car accident. Here's why. During a collision at just 30 miles an hour, a 20-pound child suddenly weighs hundreds of pounds because of the tremendous forces involved. No adult can physically hold onto a child during that type of impact. Today's recommendations from the American Academy of Pediatrics emphasize using the correct restraint for the child's age, weight, height, and developmental stage. Children should remain rear-facing as long as possible until they reach the maximum height or weight limit allowed by their car seat manufacturer. Rear-facing seats provide the best protection for a young child's head, neck, and spine because they distribute crash forces across the entire back. And I've heard all the concerns. But my child's legs are squished. They don't like facing backwards. I turned my older child around when they were a year old. And I empathize with these concerns, I really do. But keep kids rear-facing as long as possible. I would much rather help a parent navigate a child's broken leg than a broken neck after a motor vehicle accident. Once children outgrow the rear-facing limits of their seat, they should transition to a forward-facing car seat with a five-point harness and remain there until they reach that seat's maximum height or weight limit. After outgrowing a forward-facing harness, children should use a belt-positioning booster seat until the vehicle's seat belt fits properly. For many children, this does not happen until they are 4'9" tall, often between 8 and 12 years of age. A seat belt fits properly when the lap belt lies low across the hips, not the abdomen. The shoulder belt crosses the middle of the chest and shoulder, not the neck or face. The child can sit with their back against the vehicle's seat and knees bent naturally over the edge without slouching. Sitting in the backseat is safest. Children younger than 13 years old should ride in the backseat whenever possible because front-seat airbags can cause serious injuries to younger children. And I realize that many cars come with a feature that enables you to turn off the front-seat airbag. Don't do it. One important reminder. Car seat laws vary by state, but best-practice medical recommendations are based on your child's size and developmental readiness, not simply the minimal legal requirements. Your pediatrician or a certified child-passenger safety technician can help you determine when your child is ready for each transition. Moving on, I still hear parents routinely say, "We never wore helmets and we're fine." Fair enough. Many are. But thousands aren't. Traumatic brain injuries remain one of the leading causes of death and disability in children in the United States. Helmets dramatically reduce serious head injuries. Helmets should be worn every single time a child rides a bike, scooter, skateboard, rollerblades, ATVs, snowmobiles, and when skiing, snowboarding, or horseback riding. A properly fitting helmet should sit on the head, not tilted back, located two fingers above the eyebrows. The side straps form a V around each ear, and chin straps are snug enough that only one or two fingers fit underneath. Replace helmets after a significant crash or if the manufacturer recommends replacement after impact. It's also important to remember that helmets reduce risk. They don't eliminate it. Children should still ride age-appropriate equipment, follow traffic rules, use adult supervision when needed, and avoid risky behaviors. For ATVs in particular, pediatric experts recommend that children younger than 16 generally should not operate adult-sized ATVs because of the high risk of severe injury. There are many more examples of how parenting recommendations have evolved. Smoking around children is one of them. For many years, smoking in homes, cars, restaurants, hospitals, and even on airplanes was common. Today we know that secondhand smoke increases the risk of asthma, ear infections, pneumonia, bronchiolitis, SIDS, and long-term cardiovascular disease risk. Smoking and vaping, whether it be products that contain nicotine or marijuana, impair the function of the lungs. I often wonder why parents who use these products don't make the association that their habit is causing their child to be sick. Other examples of recommendation change include the use of sunscreen, the importance of water safety, internet safety, discussions regarding strangers, sleepovers, and even child trafficking. As we wrap up today's episode, I want to leave you with one final thought. If you are a grandparent listening, please don't hear today's episode as criticism. The overwhelming majority of parents have always wanted the same thing. Healthy children. Safe children. Happy children. You parented with the knowledge you had. Today's parents are parenting with the knowledge they have. And 20 years from now, some recommendations will probably change again. So please be open-minded. Because every scientific discovery gives our children an even better chance to thrive. One of the greatest gifts that we can give our children is imperfection. It's humility. The willingness to learn. The willingness to change. The willingness to say,"I didn't know that then, but I know it now." And that is how parenting and medicine continues to improve.
