A mum has described the horror of discovering her little boy had fallen out of a bedroom window and landed on concrete 12ft below.

Little Leon Young, three, smashed his head on the ground and suffered a fractured skull.

He was flown by air ambulance to a specialist London hospital for emergency treatment where he was kept in intensive care for three days.

But miraculously the youngster appears to have escaped any permanent brain damage following the accident at a first floor flat in The Grove, Barham.

Mum Stacey Jervis, 22, said: "Leon was playing in his bedroom with his older sister Ruby and another friend.

"Somehow a window was opened and toys were thrown out. We think Leon just climbed up onto the sill and must have toppled out.

"I was actually in the loo when my brother Warren shouted out and I heard the commotion. I came out and rushed downstairs to the back garden where Leon was lying on a concrete path.

"He was crying and there was a lot of blood coming from his head. He had a huge bump. It was a terrible sight and I was very scared because he looked in a really bad way."

Her brother Warren, 19, jumped out of the window after Leon and landed heavily, spraining his ankle.

He said: "It was just a reflex reaction - I wanted to get down to him as soon as possible."

An ambulance was called and paramedics quickly assessed that Leon needed to go to a neurological unit as soon as possible.

The Kent Air Ambulance was scrambled and less than 40 minutes later Leon was getting specialist treatment in King's College Hospital.

Stacey and Leon's father Martin Young, a soldier based at Lydd, drove to London to be at their son's bedside - where they stayed for six days.

He said: "They did several brain scans but no significant bleeding was found which was a miracle and huge relief.

"Even the doctors said he had been very lucky but they kept him in for six days to be sure no problems emerged.

"Apart from a few scratches and bruises he seems to have escaped without any serious injuries."

The accident happened last Wednesday morning, but Leon was allowed home on Tuesday afternoon.

Stacey said: "It's amazing because he seems right back to his normal cheeky chappy self and I am hoping he can return to Barham pre-school next week.

"Of course, we shall be keeping a very close eye on him and he does have to go back to the hospital for a check-up next month."

She added: "We can't thank the doctors and nurses enough because they were brilliant. We had a room with Leon and didn't leave his side for six days.

"We also want to thank the Kent Air Ambulance for getting him to hospital so quickly. We shall certainly be supporting them in the future."
