Jenson Button's pregnant fiancée Brittny Ward has revealed their son Hendrix, 15 months, was rushed to hospital on Halloween after suffering a febrile seizure.
The model, 30, took to Instagram to share a snap of her little boy in the hospital bed as she explained the 'scary' moment he'd had a seizure after his temperature spiked.
Brittny, who is pregnant with her and Jenson's second child, added that in recent days Hendrix had been feeling 'much better and back to his playful self,' and she decided to share the post to raise awareness of febrile seizures.

In the lengthy post, Brittny wrote: 'The Button family didn’t have the best Halloween. Poor little Hendrix ended up having a febrile seizure Saturday afternoon after a sudden spike in temperature.
'We would like to bring more awareness to febrile seizures, they are much more common than we realised.
'They often happen to infants when there’s a sudden spike in temperature and it’s the body’s response trying to regulate itself.
'If you don’t know, when a child is having a febrile seizure it’s best to keep them cool as possible and DO NOT cover them up.
'It’s also best to lay them on their side so they don’t choke on their saliva. Hendrix is doing much better today and is seemingly back to his playful self.
'Thank you to everyone who helped us in this scary situation and everyone who reached out making sure he was OK.'
