Hi @event-horizon, so sorry, I must have missed your comment last week. I know that the WHO are extremely careful on this issue so I'm confident in there safety. This reference goes into more detail on the safety issue although if you are in a high malaria location I would highly encourage the use of the nets with your children. Malaria is a hideous disease to go through even when its not lethal.

Lotions are good but need to be re-applied frequently as they are easily rubbed or sweated off.
