"It's one of the best things I have ever heard, I couldn't believe it. What is the chance of getting a baby back after six minutes?" Chelsie says.
The parents name their baby Yasin, and four months after his birth the cute tot is thriving and healthy.
In difficult to watch scenes captured by the More4 cameras, the baby's father, Mohammad, is unable to do anything but watch as the paramedics use their thumbs to give the baby CPR.
The baby lies motionless on the floor of the room as they administer a suction pump to his mouth.
"After three minutes your brain is starved of oxygen. The chances of survival become a lot less,' Chelsie warns in the clip ahead of the programme which airs tonight.
"There's a small suction unit in the maternity pack, that you have to suck on to clear the baby's mouth and airway," Chelsie explains as the dramatic scenes unfold.
Luckily just seconds later the tot gives a weak cry just as Chelsie and Simon cut the baby's umbilical chord.
An emotional Mohammad is thrilled to hear his new son's first cry, while Chelsie and Simon relive the wonderful moment.
"You're waiting for that initial cough, that snort, that cry anything," Simon says.
The paramedics wrap a blanket around the baby and rub it to warm him up as Simon adds: "It's not over by a long shot.
"But it gives you hope that the baby is fighting as hard as you are."
