Two Westchester moms allegedly took a major chance with their children's lives by driving under the influence with them in the car over the weekend in separate incidents.

Police say they pulled over Siobhan Fahy, of Brewster, at about 2:30 a.m. Monday after she drove erratically on the northbound side of the Saw Mill Parkway. They say the 29-year-old mom, along with 31-year-old Juan Fernandez and two children, ages 4 and 9, were in the car. According to police, the car reeked of marijuana. They also say Fernandez had three bags of marijuana and one bag of cocaine in his boots, and another bag of cocaine hidden in his rectum.

A 41-year-old Maopac mom, Deborah Havir, is accused of colliding into a tree on Route 118 in Somers Saturday night in a separate incident. Police report Havir's three small children were in the back seat after she left Charles Tavern intoxicated. Havir allegedly fled the scene, but a tip from witnesses led police to her location.

Havir and Fahy are charged with DWI and endangering the welfare of a child. Fernandez faces drug possession charges, among others.
