We love to interact with our readers on Facebook. If you're not a follower on our Facebook page yet, now is a great time to join us. We periodically conduct giveaways to great St. Louis family attractions directly from our Facebook page, and this week, we're giving away four tickets to see Nick's Storytime LIVE at the Fox Theatre on July 16. You can view and like our Facebook page here.

This week's contest is called BRING IT. The Facebook friend that brings the highest number of followers to our page by Friday at 3 p.m. wins the tickets. It's that simple. And they're great seats!

In previous Facebook contests, we've given away tickets to Cardinals games, kids CDs, and more.

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.
