His dad, Liam Mather, told the BBC: “Reuben had no health issues, he’s a normal little boy, loves football, loves sport.
“As he was walking into the bathroom with his mum, he put his hand on his head and grimaced as though he was in pain.
“Everything seemed okay and he got in the bath – a couple of minutes later, she noticed his bottom lip on his right hand side started to drop and he couldn’t seem to get out of the bath.
“She called 999 and got an ambulance there.”
Reuben is currently undergoing treatment at Birmingham Children’s Hospital, where his family says he is showing promising signs of recovery.
