Here’s a pop question: Could you pass a grandparenting class? It may sound silly, but a growing number of parents-to-be don’t think their parents are up on the latest baby-raising intel. So, they’re enrolling them in grandparenting crash courses, which are being offered at hospitals across North America.

So, what do you learn in Grandparenting 101? Janet Bowen teaches classes at Washington State hospitals. And she says the material covers everything from preparing a bottle, to tips for assembling and installing newfangled new baby gadgets, like a sleep sack or rear-facing child car seat.

And experts say the courses can even potentially save lives. That’s because grandparents often serve as a default baby sitter.  And there’ve been a lot of updates in child safety in the last 20 years or so, since they were raising their own babies. So, the courses fill in a lot of potentially lethal gaps. For example, 30 years ago, parents were taught to place babies face down in their cribs to avoid Sudden Infant Death Syndrome. But today, new research shows that face up is safer.

So, grandparents-to-be, if you’re interested in a baby refresher course, call your local hospital to learn more about classes.
