"I can probably count five breaths in about a minute when I was holding her, she was gasping for her last breaths".
When contacted, AirAsia confirmed there was a medical emergency involving an infant on board its Flight D7236.
An AirAsia spokesman said the plane was met by police and paramedics when it arrived at Perth airport on Monday morning.
A baby died during a flight from Kuala Lumpur to Perth on Monday (April 22) morning, reported Australia's ABC News.
"Our thoughts are with the infant and family involved".
"I said to them if you need any help, I'm happy to, you know, give a cuddle", Ms Parenzee, pictured, said.
A woman who held the infant who died on a flight from Malaysia to Perth has told of the moment she felt the child's body go "limp" and the "chaotic" two-and-a-half hours that followed.
"The parents offered the baby to me with desperation in their eyes", she wrote on social media.
'At the start of the flight the baby was really restless and cried continuously.
Ms Parenzee said what followed was two-and-a-half hours of "chaos", with resuscitation attempts continuing until the plane landed.
"She was grey in colour and she was struggling to breath, so I said a little prayer".
"To the unbelievable staff of AirAsia you were wonderful and I commend your professionalism".
The AirAsia flight D7237 landed at Perth global airport at 5.30 yesterday morning, and was set to take off again at 6.50am.
WA Police said the baby girl's death was not being treated as suspicious.
The death is now under investigation while a report is prepared for a coroner.
"The safety and wellbeing of our guests is always our number one priority, and in accordance with procedure, the flight crew requested medical assistance on landing", he said.
The aircraft's return flight to Kuala Lumpur at 6:50am was delayed as police continued their investigations into the matter.
The airline apologised for any inconvenience caused by the delay and said it would assist guests in re-booking.
