A study suggests that a new approach to baby-led weaning is safe and has some benefits. With parent supervision, babies can feed themselves solids without a spoon — foods that they can pick up and get into their mouths, but that are also low risk for choking. Benefits of this approach include babies starting solids when they’re ready rather than when parents are ready and babies learn early to be in charge of what and how much they eat.

It’s surprisingly easy to give a child an incorrect dosage of liquid medication, and many parents do. When giving medication to a child, be sure you understand the instructions and use a medication syringe rather than a dosing cup. Take the extra time to read and think, and ask questions. These simple steps can make all the difference.

Choosing to vaccinate a child — or not — doesn’t just affect that child, but also undermines the concept of herd immunity that protects others in the community from the spread of certain diseases.

A study found that parents of newborns frequently do not follow safe sleep guidelines for their babies even though it’s likely they are familiar with them. The most common mistake is putting blankets or other items in a baby’s crib, but cribs should be empty. While it’s hard to imagine sleeping on a bare mattress, babies really don’t need bedding. And it’s not worth risking your baby’s life for the sake of a blanket.

About 10 people die from drowning every day. Of these 10 people, two are children. For every child that dies from drowning, five other children are treated in hospitals for injuries sustained from drowning. Although swimming can be a dangerous activity for even the most experienced swimmer, there are ways that parents can help protect their children from the dangers of drowning. Fencing off your pool, teaching your child how to swim and simply being observant of your child in any sort of water are all easy steps to help keep your child safe.

After recent mass shootings, terrorist attacks, and other reports of danger, it is almost impossible to avoid depictions of violence on our nightly news screens. Between the use of mainstream media and social media, violence is reaching far past the places and people it directly affects. Unfortunately, this means that the violence of the world is also affecting our children. The American Academy of Pediatrics wants people to understand exactly how exposure to violence can affect children, and how we can work to decrease the impact it has on today’s youths.

As temperatures around the U.S. continue to rise, it’s important for parents to recognize the risks that sunny summer days can pose to children. Heat exhaustion and heat stroke are some of the most common issues overheated children may face, but simple measures, like taking rest breaks in the shade, watching the weather forecast for excessive heat, and drinking cold water can help keep children safe during the sunny summer days.

It’s no surprise that children suck their thumbs or bite their nails. These behaviors are often discouraged, as they can go on to cause damaged teeth, infections, or even elicit teasing from other children. However, a new study suggests that there are benefits for children who exhibit these behaviors, as it makes their immune systems better at attacking germs and decreases their risk of developing common allergies. Although these habits may be irritating for parents, they may improve your child’s health in the long run.

There are a wide variety of sunscreen products on the market today that can help to prevent sunburns and skin cancer, but in a recent study published in the journal JAMA Dermatology, researchers found that 40% of the top 65 most popular sunscreens didn’t meet American Academy of Dermatology guidelines. When buying sunscreen, it is important to choose a product that is broad-spectrum, has an SPF over 30, and is water resistant. In addition to choosing the right sunscreen, it’s important to use it correctly in order to truly protect your skin from the sun.
