Her son's head is flattened on one side.

Marnie Simpson has revealed her baby boy Oax has a skull disorder called plagiocephaly. The mum opened up about her son's diagnosis after her followers noticed his head was flattened on one side. Marnie explained that due to her son's position in the womb, he developed torticollis. This means her baby boy cannot move his head to the left. The former Geordie Shore star is hoping he can fix this with physio appointments, but there is a long way to go. She told her followers, "This condition has left him with plagiocephaly. The head is flattened on one side, causing it to look asymmetrical. "This can cause the ears to be misaligned and the head looks like a parallelogram when seen from above. "Sometimes the forehead and face may bulge a little on the flat side." Marnie explained that she wants to be open about this process because so many parents are afraid to talk about it. She wants any mum or parent going through the same to feel less alone as they get through this difficult time. The mum said she was shocked when she noticed the "severe side" of her son's head, but he will be fitted for a helmet which will hopefully help Oax. "I’m being open about his process as I know so many parents don’t even know about this issue. "He’s had his measurements taken yesterday and in 2 weeks he’ll get his helmet fitted this," she shared. Marnie said her son will make progress with treatment. Treatment usually starts when your baby is 4-6 months old because their skull is still soft then.
