Chrissy Teigen's Twitter is flooded with pictures of children in their corrective helmets.
The thread took off yesterday when Teigen posted about her son with singer John Legend having to wear a corrective helmet for what's known as flat head syndrome.
She said baby Miles is "probably gonna be cuter with it somehow."
Hours later, Teigen posted a photo on Instagram showing him wearing the white helmet.
Parents across social media then began posting photos of their own helmeted children to Twitter. Teigen said they were "very sweet."
