Little Jonas Gutierrez, four months, suffers from severe plagiocephaly or flat head syndrome. The condition means he has a flat spot at the back of his head and the skull is also being pushed out at the sides. Doctors warned that the cute tot would end up with asymmetrical facial features unless he wore a helmet to correct the deformity. When he came home wearing his new accessory for the first time last week, his big sister Camila (corr), three, noticed straight away - and wanted to wear her helmet too.
