Either illinformed opinion or closet racism.
Just because people go to take advantage of much cheaper medical procedures, does not mean the infrastructure is necessarily great. I for one, would not want to risk anything happening to a small child, when the nearest decent medical facilities are a long way away, and the place you’re in may not be particularly accessible.
A lot of Thailand’s excellent medical facilities are geared up to providing cheap operations; notably, ‘gender-reassignment’ and laser eye surgery. Not particularly useful, when your small child has picked up some nasty bug, been bitten by something poisonous, or has a nasty injury. Plus, most of these facilities are in the major cities, and you could be a long way from there.
It’s still very much a third-world country, and as such, possibly a bit of a risk, where a small child is concerned.
The OP will, I’m sure, be thinking of the health and safety of his family. That’s why I offered up my opinion.
Anyways, loads of nice, quiet family-friendly places in Europe.
