Ayana McClinton, 31, faces one count of child endangerment and another count of injury to a child, according to court documents.
The Harris County Sheriff's Office said deputies responded to a 911 call at around 6:40 a.m. on 12062 Veterans Memorial Drive after someone reported seeing the woman and her babies lying on a sidewalk.
HCSO said the 30-year-old mother showed signs of intoxication, and she decided to take a nap outside on the ground with the outside temperature around 28 degrees.
Authorities said the woman had an open alcoholic beverage near her.
First responders arrived and treated the 2-month-old and 1-year-old babies, who suffered cold-related injuries while lying outside under a blanket.
"CPS is investigating this incident alongside law enforcement. I'm happy to report the children are healthy and safe. They've been released from the hospital to the care of a family member," a spokesperson with Child Protective Services said in an update around 6 p.m.
