I have used one of your recommendations with my 20 month old. I took annatto out of her diet and I don't know if it's a coincidence but I definitely saw an improvement in her tantrums and she no longer hits herself on the head or scratches her face when she has a major meltdown. She is much more manageable when she has a tantrum and she doesn't get as upset or angry and not for as long as she used to a couple of months ago.

The items she was eating almost every single day for nearly 2 months were : Lay's Quavers cheese flavoured potato chips Pepperidge Farm baked cheddar cheese goldfish -only a little handful or so as a treat or in the car/shopping trolley, but still even a little amount adds up! The tantrums and head hitting also started around the same time I started giving her those treats - 19 months. Now she is just a couple of days off 21 months and she still has screaming tantrums, but nowhere near as severe and not with headhitting, scratching her face or full on flailing limbs. Also the amount of tantrums had definitely decreased. Thanks again and keep up the good work! :) - Vicki from UAE (report received September 2011)
