A mum was shocked as her 'large baby girl' was born with one body and two heads.

Ket May, 35, had no idea she was going to give birth to conjoined twins as it went undetected throughout her pregnancy.

Her twins, who weighed around 15lbs at birth, are currently fighting for their lives in hospital and Ket says she 'wants to be happy but is also distressed'.

One of the heads has the ability to move while the other has remained still.

The mum had been expecting a large baby when she went into labour on March 3 in the Siem Reap province, Cambodia, reports the Mirror.

The babies emerged feet first causing doctors to perform a caesarean section.

But they were stunned when they saw two tiny heads joined together on the same female body.

Ket is still recovering from the difficult birth with the father Kam Sary, 40, at her bedside at the Kantha Bopha Children's Hospital.

She said: ‘I want to be happy but I am also upset. I don't know why this happened. The baby is not strong.

‘My feelings are confused. Yes, I'm happy to have a baby girl but I am distressed, too.

‘I do not know if she will survive. We don't know what to do.’

The conjoined pregnancy went undetected as the mother never had an ultrasound scan, which costs the equivalent of around £10 in the South East Asian country.

The parents, who have three other children, are from a village in the remote Battambang District of the region with limited access to normal prenatal checks.

The girls are being fed through tubes and kept in an incubator while she is cared for round the clock.

Medics said they are monitoring their condition before deciding what to do next.

A hospital spokesman said: ‘The baby has a very weak heartbeat. The mother is also exhausted from the birth. She is also shocked.

‘Doctors have not allowed the baby to be taken home and we have her at the hospital.

‘The birth has surprised a lot of people at the hospital. We have never seen this before or dealt with the condition.

‘We are very cautious about the health of the girl. We are still waiting for a specialist in the condition.’

The spokesman added: ‘The doctors and nurses here will do everything possible for the young child.’
