Flipkart advertisements have found a great following. Many of us (and yes that includes me) love the concept and the script for the commercials on air these days. Nonetheless, I know where from the idea of using babies/toddlers as actors and voice over of adults comes from. While in US, I saw commercials of E*trade, which is is online trading portal. The commercials have babies with adult voice overs.
Here is an E*trade commercial.
