My wife and I, plus our 2 year old are thinking of going to Sao Paulo and Rio.

I've done some reading on the safety aspect, if it was just two of us minus little one we would not be too concerned. So I have found the following:

- Avoid wandering around at night
- Avoid beach areas at night
- if in the event of a hold-up, just hand over your stuff without resistance
- pickpockets are quite rife but then most cities in the world are too.
- don't flash the bling
- Daytime stick to mainly tourist areas
- taxis are safe
- Metro's are safe

As far as I can see they seem quite standard rules for most places in the world.
Weighing up the risk and reading other threads, everything should be fine, just be street wise and act where you know where you're going.

Anything else I need to think of?
