Ask your nephew. Also mention that he would not understand the teachers or other kids as they will speak panjabi. Food will be different. Might even get travelers diarrhea. Ans there is also more mosquitos and chances of dengue and malaria.
So I would ask your nephew and his parents. And also see if Dylan is resilient and of a hardy constitution.
Would Dylan not miss his parents or his friends in Canada? Or become homesick?
It would be great if Dylan went and learned panjabi and got to travel at such a young age and c experience a different religion and culture and land.
But would he be able to handle it? Just ask him do you want an adventure? And tell him adventures are not fun but are exciting. There is danger and trouble and terrible odds. But it's never boring. Look in books adventures are usually disease getting lost almost dying and fighting wild animals to dangerous ppl etx
