When my boy 0-2yo, he was on pure organic foods (other than milk, meat & fish). We used to order in bulk (share with my aunt) or buy at Tanglin Mall.
Now he's older and his organs are more mature, we are slowly cutting back on the organic food. This is because children who are not exposed to non-organic food from young will develop adverse reactions when they take non-organic food. I have a cousin who ate organic food all his life because non-organic food will cause him to have severe vomitting.
But for veges that have large surface area & those that can horde alot of chemicals like spinach, i will still choose to buy organic.
