I agree with @mage Since you are wanting to play with a kid go for 5th Edition. Some may prefer older editions for various reasons but 5th is definitely the most kid friendly. For starting 5th Edition the best place is the ‘Lost Mine of Phandelver’ starter set. It has everything you need to play. If after going through that adventure you want to delve deeper into 5th Edition then his recommendations on what to get next are also good (Players Handbook and Monster Manual are more or less required, Dungeon Masters Guide and any of the Campaign books  and later supplements are optional).
