A TOOWOOMBA mother received the shock of her life when she gave birth to a baby girl in her sister's bathroom in Harlaxton.
Mother-of-three Liza Chilly, 28, was ecstatic that baby Summer was happy and healthy despite how she entered the world.
Ms Chilly said she could not believe how quickly she had given birth.
"I was shocked when I realised I just had just given birth on the bathroom floor. I didn't even know a labour that quick was possible," Ms Chilly said.
"Thankfully, it all turned out well in the end and Summer is as healthy as can be," she said.
Ms Chilly was bathing her dog Sunday afternoon when her she first began having contractions.
Because she was one week overdue, she was not sure if it was another false alarm.
"I was home alone when everything first started so I went to my sister's house," Ms Chilly said.
"Being overdue, I couldn't tell if I was having serious contractions, so we timed them and they were one minute apart.
"That's when we decided to call the ambulance.
"We obviously called a few minutes too late because my sister had already delivered Summer when they arrived," she said.
Ms Chilly's sister Emily Cooper, 24, said she was scared when she first realised she had to deliver a baby in her own home.
"I had just called the ambulance when Liza yelled out to me from the bathroom saying she had to push," Ms Cooper said.
"The (ambulance) dispatch officer helped me through delivering Summer and I know I wouldn't have been able to do it without her.
"It was all over in just a few minutes.
"I didn't realise how scared I was or how much I was shaking until I got off the phone.
"I suppose there is no time to be scared when you're delivering a baby," she said.
Emergency medical dispatch Officer Christine Phillips stepped Ms Cooper through the home delivery and said it was an exciting call to receive.
"In my profession, you don't always get calls that have such a good outcome, so I was happy to assist," Ms Phillips said.
"When I first received the call from Emily, she was panicky, but eventually she calmed down and did a fantastic job.
"We are trained to assist while the ambulance is on the way.
"It's our job to assure whoever we are speaking to that it will be okay and give instructions to help successfully deliver the baby," she said.
Ms Chilly and her daughter Summer were taken to Toowoomba Hospital where they will remain in the care of the midwives until tomorrow.
