The Studies Show LIVE (with special guest Jesse Singal) is this week! Friday 9 May, Conway Hall, London, 8pm. Get your tickets AT THIS LINK or at bit.ly/tss_live.

Welcome to a new series of The Studies Show, all about parenting. We’ll cover the weird claims, fads, and controversies about how you should raise your kids.

In this first episode, which focuses on infancy, we cover some feeding-related topics (an update on breastfeeding, the question of sterilising baby bottles, and the idea of baby-led weaning) as well as “tummy time” and sleep training. Are any of these good for your baby? Are any of them bad? Tom and Stuart look through the evidence.

Let us know which parenting-related claims you want us to look into as the series continues!

The Studies Show is brought to you by Works in Progress magazine. In their recent issue you can find out about surprising policy screwups, the latest fertility techology, the history of the pineapple, and why all that steam comes out from the roads in New York City. It’s all available for free at worksinprogress.co.
