The lower reaches of Everest are a filthy, dangerous place which is not suitable for a child. I traveled around in some foreign places as a small child with my family and it was great, but this is akin to those parents who want to take a selfie with a bison or a bear or something. The world isn't a theme park. The places that people are attracted to specifically because they're extreme and dangerous (and at this point unsanitary and overcommercialized beyond the point of it even being a worthwhile adventure) are not good places to take your damn kid.
