If Nepali culture is so important to you, you shouldn't be raising your kids in the United States. Children who are raised here will obviously be influenced by US culture no matter how hard you try to saturate their mind with Nepali stuff.

And, what is there to be proud of Nepali culture anyway? We are one of the poorest nations, we are corrupt as hell, Kathmandu has become a pit hole with dirt and garbage everywhere, we value nepotism rather than merits, there is hardcore caste system based on birth.
