If baby is breathing, place him in the recovery position (shown above), phone 000 and check regularly for continued signs of life until the ambulance arrives.
If baby is NOT breathing, tilt his head back very slightly, lift his chin to bring the tongue away from the back of the throat, opening his airway. Take a breath and seal his mouth and nose with your mouth. Blow gently and steadily for about one second. Watch for the rise and fall of the chest. Take another breath and repeat the sequence.
If there are no signs of life after two breaths, make sure someone has phoned 000 and commence chest compressions.
