Keeping attractive coloured fruits in your refrigerator such as strawberries, grapes, dragon fruit, watermelon and bananas can be a great idea, as children love to see many colours around.
Start serving them food as per their favourite colour. If they don’t like to have white rice, you can add some vegetables to make pulao, which will have a different colour.
Serving food in colourful crockery of their choice might also attract them to eat.
