State, 769 S.W.2d 535, 536-37 (Tex.Crim.App. 1989) (stating an allegation that defendant caused serious bodily injury to a child by placing him in hot liquid provided sufficient notice that State would seek affirmative finding of use of deadly weapon); Ex parte Beck, 769 S.W.2d at 526 (<HOLDING>); Pena v. State, 864 S.W.2d 147, 150-51
