A couple was stunned when their son's birth was so rare that their midwives had never seen it.
Jennifer Petrie welcomed her first child with Theo Martins on December 16.
But the new baby was born as a'mermaid', a rare occurrence in the UK.
Jennifer told the Liverpool Echo she was confused when her waters didn't break. break.
Having given birth in a birthing pool in Southport, Jennifer travelled to Ormskirk Hospital with Theo, 32.
said: "My water never broke. The amniotic sack where water gushes out during labour never broke, which is remarkable. The infant was still in the balloon when born.
"He appeared to be born in a water balloon. Because it was a water birth, the baby's amniotic sack leaked into the pool. He appeared to be cocooned. It only burst when he was taken up and birthed." The midwives were shocked because it is so rare that many midwives never witness it in their career.
"The midwives said 'oh my god this is great'. It's so rare that many miss it."
They took it as a sign of good luck because there were no difficulties and Jennifer was not in agony.
The birth, also known as a mermaid birth or an en caul birth.
Theo: "One midwife had seen it previously, the other two hadn't. They said it was 1 in 100,000 or so."
Irene stated "It made it more wonderful because everyone was in amazement of what was going on and expressing how lucky and amazing it was.
"It was also our firstborn child, which added to the joy and excitement, especially with all the fuss. It was lovely."
