I am a big believer in any time spent reading is time well spent. Whatever you can do at home to encourage reading for pleasure is greatly appreciated. For the last few years I have had interested kids fill out a Google form to share what they're reading and I will continue with that tradition. Remember - books read independently, together with a family member or friend, or a book that is read to kids (including audio books) all count.
