For years, many kids could skip the traditional flu “shot” — along with the tears — and still be protected by the nasal spray vaccine also known as the LAIV (live attenuated influenza vaccine). But not this year. Studies now show that the nasal vaccine is quite ineffective, and pediatricians are starting to change their flu recommendations from a nose squirt to a shot.

Research suggests that super-sizing our meals doesn’t just create problems for adults–– when we increase the amount of food that infants and children eat, they gain weight. This weight gain during infancy can lead to over-weight children, and over-weight children are more likely to become over-weight adults. In order to make sure infants and children are a healthy weight, keeping the portion sizes kid-friendly is key.

When your child has a stomach bug, it’s tempting to reach for over-the-counter oral rehydration solutions. After all, doctors have recommended them in the past. But a new study has revealed that most children don’t need them. In fact, juice diluted with water may be all your child needs.

3 reasons your child shouldn’t go “gluten-free” (unless your doctor says so)

Recently, many parents have begun cutting gluten (a protein found in wheat, rye, and barley) out of their children’s diet in an effort to be healthy. Although children with celiac disease or wheat allergy should avoid gluten, a gluten-free diet is unnecessary for the vast majority of children — and it can even endanger their health. We’ve identified three specific ways this diet can do more harm than good for your child.

Just about every new parent has wrestled with the idea of whether to comfort a baby who cries during the night or whether to let him or her “cry it out.” A recent study adds more evidence to what researchers (and our own parents and grandparents) have long known: It’s okay to let your baby cry it out. It won’t harm them — and you’ll get a much better night’s sleep, too!

Swaddling a baby—wrapping him or her tightly in a blanket to give a sense of comfort and security—has been practiced for millennia. But it’s not right for all babies. In particular, several studies have revealed that swaddling can potentially cause problems hip problems and can even be dangerous if not practiced correctly. As always, if you have questions about swaddling your baby, it’s best to talk with your doctor.

If you’ve looked up from your phone recently — or even if you haven’t! — you may have noticed that many children and teens are glued to their devices. While experts aren’t quite ready to call this an “addiction,” a new survey of parents and teens confirms that many of them suspect they’re too dependent on their devices. We’ve discussed the potential implications of this, plus suggested some “ground rules” for when to ignore those devices.

You may have noticed that many playgrounds are now “safer” than they used to be. It’s great to think about safety, especially since there are hundreds of thousands of playground-related injuries every year, and a significant chunk of those are brain injuries like concussions. But it’s also important not to get overprotective — some life lessons about risk and self-confidence are best learned in a fun, stimulating, well-supervised environment like a playground.

A new law in North Carolina prevents transgender people — people who feel very strongly that their biological sex does not match their true gender — from using the public restroom of the gender they identify with. But the American Academy of Pediatrics has denounced this law for discriminating against transgender children and children with certain genetic disorders. As they say, what all children need the most is unconditional acceptance and support.

How much should teens weigh to prevent heart disease as adults?

We know that overweight teens have a higher risk of heart disease throughout their life, which is why pediatricians make sure to discuss healthy lifestyle choices with their patients. However, a recent study reveals that the weight ranges currently considered acceptable for teens might be too high, and therefore still putting them at risk. We’ve summarized the results and given you some ideas to help your teen lead an active, healthy lifestyle.
