We didn’t know it was bring your kids to work day.

A Milwaukee woman celebrating her 37th birthday with a 17-year-old son visiting from Chicago went on a robbery spree with him Tuesday night, police said. Mom drove the getaway car while her son robbed a gas station in Milwaukee and another in the suburb of Greenfield within an hour, according to police.

Also in tow were the woman’s 13-month-old daughter and 10- and 14-year-old sons, police said.

“This is a first,” said Greenfield Police Chief Francis Springob of the alleged armed robberies. “Good grief, it’s really a sad situation when you’re celebrating your mom’s birthday [like this]. It’s one of those where you’re almost like ‘You’ve got to be kidding.’”
