Mesosilver would be the best choice of the two (and in my opinion Mesosilver or Utopia Silver would be the best choices of any silver solutions).
Try this exceptional remedy for earaches (though you may have to use a small cotton ball in the ear if you have problems keeping the toddler still):
Colloidal silver, garlic, tea tree oil, olive oil and apple cider vinegar. Mix together three drops of tea tree oil with a two tablespoons of olive oil, a teaspoon of colloidal silver and a teaspoon of apple cider vinegar. Warm slightly and then lie on your side with your head on a towel (or paper towels) with the infected or aching ear facing up. Use an eyedropper to draw up the mixture and then slowly fill your ear to near the top. Continue to lie on your side for several minutes and the take the towel and hold it to your ear and lie on your other side and let the mixture drain out of your ear onto the towel or paper towels. Repeat two to four times daily. You should experience immediate relief and complete resolution within 24-48 hours. Note: If you do not have all of the ingredients, any combination will probably work. Also, oil of oregano can be substituted for the tea tree oil (but it may sting a bit).
