The alert was sent out just before 4 a.m. Saturday and then discontinued just before 8 a.m.
The Bexar County Sheriff's Office said the children were recovered safely and that Jacklyn Davidson was taken into custody. Deputies said they're still looking for Jaime Davidson, but attorney Derek Ritchie said he anticipates Jaime will turn himself in later today.
We've removed the pictures and names of the children from the post for their privacy.
What to do when someone goes missing
Thousands of people go missing every year across the United States, and there are organizations and law enforcement agencies that work to bring them home to loved ones.
The Texas Center for the Missing is an organization with Houston roots that works to educate loved ones and authorities on finding the lost.
From resources that deal with missing children to endangered adults, the non-profit organization has compiled a wealth of resources to help.
There is no 24-hour waiting period required to report a person missing, according to the Harris County Sheriff's Office.
