I’ve been hearing a lot of buzz about sunscreens among my friends. Turns out some contain ingredients that may disrupt the way hormones work in our bodies or actually do more harm than good when it comes to skin cancer.

With all the unknowns around increasing rates of everything from autism to type 2 diabetes in kids, a lot of parents are nervous about everything that goes onto and into their children. A few years ago, I was hearing similar “what-if” stories from the eco-parent types who were avoiding plastic drinking cups and bottles due to concerns about bisphenol A (which the government’s National Toxicology Program puts in the “some concern” category for developmental toxicity). Back when they first started talking about BPA, few of us knew what it was – and now, of course, BPA is pretty much a household term among families with infants and toddlers.  I suspect things could go the same way for oxybenzone in sunscreens.

Last week there was a major conference of sleep researchers in San Antonio, Texas. Usually reading through scientific abstracts like the ones presented there is a sure-fire way of inducing drowsiness, but I found several that actually made me sit up and pay attention.

The most interesting one looked at around 8,000 preschoolers to find out whether their bedtimes and how much total sleep they got had any effect on their overall development. My youngest son just turned 4 today, so I was curious—and I was surprised by what I learned.

The results may surprise you, too. But first, a pop quiz on how well you know your bedtime facts.

Each day, our kids are blasted with ads for greasy, cheesy, sugary, processed foods. It’s no wonder they turn up their noses when you present them with a bowl of veggies. Unless, of course, the vegetables are deep-fried and doused in Ranch dressing.

One way to get kids involved in making healthy choices is to bring them back to square one – and that’s in the garden. When children play a role in growing their own food, they’re more likely to eat their fruits and vegetables and learn a new sense of responsibility.

“Gardening teaches kids about being care givers,” said Gwenne Hayes-Stewart, executive director of Gateway Greening, via e-mail. Her organization promotes gardening partnerships for community development. “Consequences of poor care are evident nearly at once. Just as apparent are the consequences of paying attention to what plants need. Kids pick up on this quickly. No water, the plant dies. Too much water, the plant struggles. Making sure to check the soil first, and bingo, success!”

You still have time to introduce your kids to the benefits of gardening this summer. Although it’s getting too late to plant many fruits and vegetables, you’re only a few steps away from a delicious harvest this autumn.

Said Debbie Tolstoi of Garden Heights Nursery by e-mail, “In August, sow seeds for the fall season such as spinach, carrots, collards, kale, lettuce, beets, turnips, radish, cilantro and dill. Broccoli, cabbage and cauliflower plants should be available in nurseries in late August or early September.”

I know what you’re thinking, because I’ve thought it myself – planting and maintaining vegetables sounds like too much work. Believe me, I definitely don’t have a green thumb – it’s more like the black thumb of veggie death. However, Tolstoi had some excellent tips that make planting a garden a snap:
