Kids in predominantly Caucasian countries get pretty good sleep, says a new study. Better than kids in Asian countries, anyway.

This study, led by researcher Jodi Mindell of Saint Joseph's University in Philadelphia, is the first ever to look at sleep patterns in infants and toddlers cross-culturally. The results, says Mindell, are astonishing. Here are two of them.

• Mindell found significant variability in bedtimes and total sleep time. For example, 15.1 percent of children in Canada shared a room, compared to 94.5 percent in Thailand, and the percentage of parents who believed their child had a minor or severe sleep problem ranged from 11 percent in Thailand to 76 percent in China.
  
  

• Kids in Asian countries were more likely to have later bedtimes, shorter total sleep times, increased parental perception of sleep problems, and were more likely to share a room than children in Caucasian countries. But there were no significant differences in night wakings and naps.
  
  

Mindell says her findings present more questions than they do answers, like: Why the differences? Could it be different cultural practices? And what is the impact of these differences? Seems it's time for another study.

Peanut allergies have become pretty popular. And what causes them remains a bit confusing.

When my now almost three-year-old daughter was a baby, our pediatrician told us the American Academy of Pediatrics recommended peanut consumption be delayed until age three because the allergy was believed to be developed due to repeated exposure at a very young age. But new studies suggest no relation between allergies to peanuts and when a child began eating them. This is what AAP had to say. Since the cause is still clear as mud, study authors recommend more research on the cause of early allergic reactions to peanuts, as well as successful prevention efforts.

Meanwhile, we're still eating sunflower seed butter in our house. This web page touts its similarity to peanut butter in consistency, taste and price and offers a nutritional breakdown (it does contain a bit more sugar than some peanut butters). We started when the pediatrician gave us the nitty gritty on nut allergies and we have no plans to stop. It's really tasty. I like it better than peanut butter. We pick up a couple jars every time we go to Trader Joe's. But it's also available in other local markets.

So until researchers come up with some more news on peanuts, consider sunflower seed butter as a tasty alternative that you don't have to worry about.
