I don't have kids but I never understood why some parents think that their kids have to learn about their passion, specially at such young ages. I understand this in countries where prospects are poor and your best option is stick to the family business but this is something else with different ramifications.
I'd let my kid learn about coding if he/she asks for it and is curious, otherwise I'd never try to shove it. Let kids be kids and if they become interested then be happy to be their personal teacher.
