A student nurse who helped deliver a baby in a hospital car park said she learnt what to do from a tv programme.
Maria Patrick, 31, had finished her fourth shift at Barnsley Hospital, when she heard someone screaming in labour.
"The only thing I had only seen to do with babies was One Born Every Minute," she said.
"I just got down and said I would do what I could. I was going on instinct really. I didn't really know the hospital and we don't do any training in midwifery.
"He was already coming but I had to pull him out the rest of the way. I had a baby in my hands and thought what am I going to do with him?
"I put him on her belly as I had seen them do and gave him a rub down and he started crying."
Charlie Howell was born weighing 7lb 2oz on June 14. Parents Janine Parr and Richard Howell, of Stainley Close, Redbrook, had been to hospital but decided to go home as she was not in pain.
Other people, including members of First4Care who deal with discharge of patients at the hospital, went to help.
Maria returned to her course at Anglia Ruskin University, Cambridge, yesterday following her placement at Barnsley.
"It has been a memorable experience working here."
