New Child for an admitted abuser in AZ

My sister pled guilty earlier this year to felony child abuse (or neglect or endangerment- I can't remember specifically). She lost custody of her older children who now live in another state. This is a hearing after the first of the year to determine if the state wants to severe her rights as a mother. She recently had another baby, and I am wondering can the state take the new baby away because of this charge? I don't believe the state is aware she had the new baby.
