Police said 26-year-old Jessica Bachmaier was charged late Tuesday by Erie police with endangering the child and furnishing alcohol to a minor.
Bachmaier told police and reporters last month that she believed a friend gave the girl vodka before she was hospitalized with a blood-alcohol content of 0.289 percent May 14. That's more than 3 1/2 times more than the legal level of intoxication in Pennsylvania.
Bachmaier's daughter has since recovered and police said they're still investigating the friend's possible involvement.
Bachmaier told police she gave the girl water and some baby formula, but police now believe she put liquor in the girl's sippy cup.
