(BILLINGS) Most expectant parents plan months ahead for their new baby's arrival, but Katie Lipari gave birth to her baby boy the same day she learned she was pregnant.
Lipari, 19, gave birth to baby Bentley about five weeks ago at St. Vincent Healthcare.
"That Saturday night before, we went out to Asian Sea Grill with our friends and I was in labor the whole time," said Lipari. "I just thought it was cramping, but no, I was in labor."
When the pain became too intense Sunday night, Lipari went to the emergency room and received a stunning diagnosis from the doctor.
"He did a pregnancy test and said I was pregnant, then did an ultrasound and determined I was 20 weeks," said Lipari. "He sent me home and told me to take Tylenol."
The pain did not subside that night, so Lipari returned to the hospital hours later. She learned the first doctor got it wrong.
"They determined I was about 40 weeks along," said Lipari. "My nurse checked how far dilated I was and I was 6 centimeters dilated. She's like, 'Well, you're in labor.' And I was like 'Awesome, cool let me call Jake.'"
"I was definitely in shock. I was lost for words and basically had to rush up to the hospital," said 19-year-old Jake Idstrom, Lipari's boyfriend of two years.
Once Idstrom arrived at the hospital, he learned the delivery was a challenging one.
"Her baby wasn't really tolerating labor really well though. So at one point, the baby's heart rate dropped, and we were taking her back for an emergency C- section," said Dr. Chimene Dahl, who delivered Lipari's baby.
Dahl, who has only delivered two other surprise babies in her 23 years of work, called Lipari's delivery "stressful."
"His cord was wrapped around his neck twice and he had a knot and he didn't cry when they took him out at first. So that was really scary," said Lipari.
But then, Baby Bentley breathed. He was OK.
"He was beautiful, loss for words," said Idstrom, thinking back to the moment he first saw his baby.
Idstrom said any fear he had about not being ready for this baby melted away.
"After I held him for the first time, I kind of forgot everything. I just knew we could do it from then," said Idstrom.
This young couple laughs when they think back to the little signs of Bentley that went unnoticed, like mood swings and painful cramps.
He may not have been expected, but these new parents say they can't imagine a life without Bentley.
