Great article. Thanks! Does anyone have any recommendation on how much Iodine and what kind/brand to give a 3.5 year old? I have a little swimmer whose feet and hands often feel cold to me. Her teeth also came in a bit spaced apart. I worry that she is hypo (haven't take her basal yet though). Where she is or not, I'd like her to have the benefits of Iodine supplementation. Any thoughts would be appreciated.
