Chrissy Teigen has revealed her son Miles needs to wear a helmet to fix his “slightly misshapen head”.

The model and TV presenter, who is married to singer John Legend, posted a picture on Instagram to say their son had been fitted for a helmet.

“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!”

She later joked: “I have been told it’s too late for my head.”

Plagiocephaly and brachycephaly, known as flat head syndrome, is a condition babies get often due to spending a lot of time lying on their back.

Helmet therapy is proven to fix the shape of a baby’s head as they grow.

After Teigen, 33, shared a picture of Miles in his helmet, other parents replied tweeting snaps of their own children wearing theirs.
