The baby was going into surgery Thursday morning when the call from the hospital was made to police. Police were also at the mother's apartment on Thursday.
Montgomery County Children Services officials said their office had an open investigation into the mother before Thursday's incident. The agency could not confirm how many children live in the home.

Neighbors told News Center 7's John Bedell the infant is the youngest of the children in the home.
Neighbor Letisha Hardin said she saw police cars at the home Thursday.
"Yes, when I took my kids to school this morning I noticed it was a couple police cars over there but I didn't know what was going on," Hardin said of the apartment on Elsmere Avenue.
Hardin said she knows the family.
"My kids play with their kids and so yeah it is … concerning," she said. "I would hope that nobody would hurt a little child but these days, you never know."
The mother is not being identified by name in this report because no charges have been filed.
