I’ve been using Bob books to teach my kiddos to read (starting at age 4) for 10+ years. I’m on kid 3. They build upon each other and unlike lots of other beginner reading books there are no words that are too big for beginners. I highly recommend. Have your kids read to you and their stuffed toys. Remember half the battle is memorizing words so it will seem like they are just remembering what the picture is and not actually reading but that is part of the process. Eventually when they are ready you can cover the pictures before they see the page.
