Congrats, there are some great books at a variety of prices and either funny/educational etc, rather than list them, and sorry not sure how to link but check out menkind.co.uk and see which you think would be best, there's some that will be talked about for life I would imagine, e.g "Ask your Father" by Ryland Peters (50 things your father should have taught you but probably didn't) but others are for early years etc. even if you don't see him reading them, I bet he does.
