Tesla Inc CEO Elon Musk and Canadian singer Grimes, who announced on Tuesday the birth of their first child together, plan to join a growing number of families opting for a gender-neutral parenting style. The approach has become increasingly popular as more parents reject gender stereotypes – such as dressing girls in pink and boys in blue, instead allowing children to make such choices for themselves.

Posting two pictures of the newborn, who they have named X Æ A-12, Musk said mother and baby were “all good”.Other famous parents who have spoken about their plans to raise their children in a gender-neutral environment include singer Paloma Faith and Marvel actress Zoe Saldana.
