My son wants to play Pokemon GO, is it safe for a 5 year old ?

Take a look at this article: http://lifehacker.com/a-parent-s-guide-to-playing-pokemon-go-with-your-kids-1783525769 I think it will be a fun game to play with your child. But as highlighted in the article, the game is probably geared towards teenagers and adults, so it is best that you are playing it together with your child. There are some safety concerns as well (such as not looking at the roads) being voiced out, so it is important to educate your child to observe safety while playing the game too. Have a read at the article, think it is a great guide for parents who is interested in allowing (or playing with) their children to play this game. Though it is not in the Singapore context, a lot of points are still applicable. Hope you find this useful. :)
