Iodine supplementation for my 1 year old

Hi all! I've posted before but haven't really gotten what I needed to know. I just discovered the amazing benefits of iodine. That being said, I would love to to give it to my son who is 14 months. He is 25 pounds. I have purchased the 2% Lugol's but everywhere online hasn't given me an exact dosage. I know that the guidelines for Iodine are way under than what they should be in USA. My son is being tested for autism in the next few months and would love to see if this Iodine would have any positive effects. Also, I would love to fake this myself. I am a 25 year old, 150 pound woman. I just am really unsure of the correct amount of drops I need to be giving to my son and myself. AND my fiance, who is a 210 pound 30 year old. I have been scouring online trying to find an exact dropper amount to give my son specifically and haven't found any luck. I just got he solution yesterday and am dying to give it to my son. I was reading it's .08x25(sons weight) which would come out to 2mg. Ah please help! I'm confused as to how many drops to give him from my 2% solution!
