Re: toddler vitamin recs?
My naturopath put our picky allergenic 2-year-old on this: http://www.amazon.com/Pioneer-Chewab.../dp/B0015R3E46. A half dose (one per day).
Another good one is Nordic Naturals Nordic Berries. They are gummies, but they don't have artificial colors or allergens. I also like that I can put his Vitamin D drop on the gummy. Nordic Naturals also makes a great fish oil gummy for kids, that is all natural and healthy and stuff.
