We enjoy reading, and since they were little we did reading, including audio books, to get them into stories. Eventually they wanted more than I was willing to read aloud, and started reading for themselves. The library is a great source.

Bought em a kobo for their 10th birthday. No regrets.

(Well, I have had to tell them to stop reading when I went to bed several times, but that's a good problem to have)

Edit: to answer your question, in 1st and second grade, the teachers wanted the kids to spend some time at home reading, 10-20 minutes was the goal, to practice essentially.
