Is it a boy or a girl? Cognitive neuroscientist Gina Rippon has just written a book that busts apart the notion, and the countless studies claiming, that male and female brains are different in any meaningful way.

Read more here.

This is important for you because think about the pictures you post of your child online – they might not appreciate them in a few years.

The most popular article on The Pulse this week was Why Unnecessary Antibiotics are Bad for Your Baby. In short, they can induce autoimmune disorders in the baby and create antibiotic resistant pathogens. Read it here.
