My 23 month old had the same thing, what made it go away (without drugs) is 2 cloves of garlic lightly boiled (about 2 minutes), grated, mized with one table spoon honey (if over 12 months) and one table spoon fresh squeezed lemon juice. Took care of it in a couple of days. Though I did simultaneously give vitamin D3, echinacea, and goldenseal for the immune system.
