The information contained on this website should not be used as a substitute for the medical care and advice of your pediatrician. There may be variations in treatment that your pediatrician may recommend based on individual facts and circumstances.

  • It’s normal for kids to be suspicious of new foods. In fact, many kids need to see a new food 15–20 times before trying and liking it. Offer a variety of healthy foods for the whole family, and let her choose what to eat from what you have provided. Being a short-order cook and making chicken nuggets just for her will reinforce her picky eating habits

  • Even though in general, 60 minutes of physical activity per day is a good rule of thumb, you don’t have to be active for an hour all at once. Even taking your kids outside for 15 minutes helps. So you don’t have to get in the car and drive to the park and stay for a whole hour. There isn’t time for that for a lot of parents, but there are 15 minutes before or after dinner. Taking a family walk is a start. Or try letting kids play outside after school for 30 minutes before they do homework. Some children actually focus better if they have that down time before homework. What’s most important is to start where you are and work your way up to that hour daily.

  • Focusing on weight doesn’t help children because they’re changing, growing and/or going through puberty. If you focus on weight you’re missing what’s important: behavior. Focus instead on healthy habits. Set short-term, achievable goals with your kids and watch what happens.

    Strong4Life suggests four healthy habits (but you don’t have to do all of them at once—start by working on one):

    It’s also a good idea to check with your child’s doctor about his or her weight. Your doctor has your child’s growth history, and can help you set healthy habit goals.

  • Repetitive asking (aka whining) is tough to take. And no food should ever be totally off limits; that’s too restrictive. Establish how often he can have his favorite treat, then stand firm and be consistent. Eventually, he’ll run out of steam and stop bothering to ask. But if you engage in battles or occasionally give in, he’ll be inspired to keep trying.

    Here are some quick tips:

    • Keep treats out of the house and/or out of sight. He can’t continue to ask for something you don’t have.
    • Be a role model and don’t eat junk food yourself.
    • If your child asks for a treat, calmly say, “We are not having cookies today. Would you like a piece of fruit, or cheese and crackers for a snack?”

    Once you have said no, when your child asks again, say something like “I already answered that question” and suggest something else to do—go outside and play, help make dinner—or something to keep him busy.

  • Fad diets might jump start weight loss, but they’re not sustainable, so the weight will come right back. Low-carb diets are missing the healthy nutrients found in fruits, whole grains, beans, and other healthy “carb” foods. Special diet shakes and bars are missing the nutrients your body gets from eating balanced meals and snacks, and most are loaded with sugar or artificial sweeteners, unhealthy fats, and sometimes unregulated herbs or other supplements that aren’t intended for kids. Making healthy choices is something you want your kids to do every day for the rest of their lives; unfortunately, there’s no overnight fix. You want to show and teach them how to make good decisions 15, 20, even 40 years from now, not just take the easy (and unhealthy) way out.
