Chrissy Teigen and Miles Legend

Chrissy Teigen shared an Instagram.com photo of her adorable son, Miles Theodore Stephens, wearing a shaping helmet to treat a condition known as plagiocephaly (pronounced play-jee-oh-sef-uh-lee), otherwise known as “flat head syndrome.”

Chrissy, 33, and 39-year-old singer John Legend‘s six-month-old son will have to wear the helmet to treat the common condition that occurs when soft plates on the baby’s skull form a flat spot at the back of his head when he lays in one position for too long.

Chrissy noted that her son is wearing his helmet to reshape his “adorable, slightly misshapen head”.

The Sports Illustrated model and “Lip Sync Battle” host revealed her son’s health update on her Twitter and Instagram pages on Monday, sharing a picture of the infant sporting a white helmet.

“Baby miles getting fitted for a little helmet today for his adorable slightly misshapen head,” she wrote. “So if you see pictures, don’t feel bad for him because he’s just fixing his flat and honestly he’s probably gonna be even cuter with it somehow.”

She jokingly added: “I’ve been told it’s too late for my head.”

In another post on her Instagram page, Chrissy shared a slightly different snap of Miles in the helmet and captioned it: “My baby bug got his head shaping helmet today! Please don’t feel bad for him if you see photos. He is a happy bug and we’re just fixing his flat!”

Chrissy’s social media followers tweeted pics of their own kids wearing similar helmets.

She commented that the snaps were “so cute”.
