Keep your baby blonde hair. Use a very deep purple toning shampoo (ie. ion color solutions cool blonde shampoo) every other time you shampoo, or more if necessary. Mix a bottle of your favorite conditioner with Manic Panic Virgin Snow toner and use every time you condition. It is semi-permanent and vegan so it will not damage your hair. Leave both shampoo and conditioner mixture in your hair for 3 minutes each. You'll see results in 1-3 uses and maintain the blonde without the yellow.
