"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."
Hendrix underwent surgery for hip dysplasia when he was aged eight months.
His parents shared images of him wearing casts on his legs and assured people that he was "doing well" following the procedure.
