Thanks @lamjung.
When it comes to kids, we worry too much.
The problem is - worrying too much disturbs the natural growth of the kids. Sending to Nepal for a couple of months is not a bad idea. But, 1-2 years is a very long time in a toddler's life.

People have different priorities. They should do what they think is the best for them.
I just meant to say that mine is to keep kids nearby and let them have a total freedom - no rules at home - until they are adults.
