A Dallas family got quite the surprise on Thursday night when their second son was born at their home with the help of their two young daughters.

Jessica Dills relived the moments right before her son, Lucas, was born from her hospital room at CaroMont Health's Gaston Memorial Hospital. She said Lucas wasn't due until Feb. 18. She expected him to come early, but not like this.

Dills was home with her two daughters and 6-year-old son on Thursday. She said she felt some pain throughout the day but thought she had time before going to the hospital. Then, that all changed.

"My water broke, I went to the bathroom to change my clothes, and that was as far as I made it," Dills said. "When I started contracting, I could feel that he was coming so I said, 'OK girls, this is it, call 911.'"

Ivy, 11, did call 911. She told Channel 9 she was frightened.

"I didn't know what to do because I was shaking from head to foot. Really scared," she said.

Issabelle, 9, also had a job.

"Well, I was helping Ivy, like, she was giving me orders to keep my other brother occupied because if he doesn't stay occupied, he will go all around crazy," she said.

In less than 10 minutes, little Lucas was born and was doing just fine. The girls brought their mom towels to wipe him off and keep him warm, and one of their shoe strings to cut the umbilical cord.

A few minutes later, Lucas's father arrived, followed by the paramedics.

"When I walked in, I'll never be as surprised again in my life,” Jamie Dills said.

The girls said they're happy they could help their mom.

"I actually find myself very proud of myself," Ivy said.

Now they're getting used to their new baby brother.

"He's adorable and cute, but his scream is kind of scratchy,” Issabelle said.  

Doctors said Lucas is healthy, and he'll be ready to go home on Saturday.
