The first step after positioning and sealing the resuscitation mask on a child is to tilt the victim's head back to open the airway. This action is essential because tilting the head back helps to align the airway, allowing for unobstructed breathing. In children, proper head positioning is crucial since their airways are more flexible and can become easily obstructed.

By ensuring that the airway is open through this positioning, it sets the stage for effective rescue breaths, as a clear pathway is provided for the breath to enter the lungs. This is a fundamental step in performing rescue breaths correctly, as any obstruction can significantly reduce the effectiveness of the lifesaving efforts.

Other options may involve steps that come later in the sequence of providing care, but ensuring the airway is open with the correct positioning is always the first priority in any emergency response involving resuscitation efforts.
