(CBS/KHOU) HOUSTON - A Houston mother was arrested and charged with child endangerment after her 20-month-old daughter was found drunk on Four Loko.

Police were called to Lashawnda Allen's apartment around 2 p.m. on Feb. 21 by Allen's roommate, who came home that afternoon to find Allen in the parking lot, talking to a neighbor while her children were inside their apartment unsupervised, reported CBS affiliate KHOU.

Allen told the roommate that the two kids were in the apartment and that her toddler was drunk. When the roommate rushed inside to check on the kids, she found Allen's 4-month-old baby hanging off the bed with the sheets tangled around her waist, turning blue. But, the 20-month-old was nowhere to be found, the station reported.

A neighbor told police she had found the toddler in the parking lot and the toddler appeared to be intoxicated. The roommate then called an ambulance, reports the station.

Allen admitted she'd been drinking Four Loko that day and had fallen asleep. When she woke up she said she saw the toddler on the floor with an empty Four Loko can, the station reports.

Allen told police she was afraid to call an ambulance because she didn't want to lose her kids, KHOU reports.

When the ambulance finally did arrive at Allen's home that day, the 20-month-old was taken to LBJ Hospital, where her blood alcohol level was found to be 0.09, court documents said.

Allen was being held Thursday in the Harris County Jail on $2,000 bond.
