She abandoned her kids to go make more.
Florida cops say Crystal Rusaw, 24, left her three children -- aged 4 years, 3 years, and 10 months -- at their New Port Richey home for hours on end so she could go have sex with the neighbor and sleep, WTSP reported.
Worse, the kids, one of whom had soiled himself, made their way to a busy four-lane highway and crossed it alone at 5 a.m. on Sunday. The 4-year-old held the 10-month-old as they dodged traffic.
A hero passerby noticed the trio and called authorities, according to ABC News.
"It could have been tragic," neighbor Joan Miller told the station. "It's just unbelievable."
Deputies arrested Rusaw on Saturday on charges of child neglect, Bay News 9 reports. Deputies told the station that she admitted to her crimes.
The neighbor she was allegedly visiting wasn't identified.
