I've used a new website this week, here is the information you need to log on. If you don't want it read to you, just put the volume down so that your child can read to you.
If you have any problems with the link above, go to this website and log in, follow the link Collins Big Cat. You should be able to find your book from here. You could also try opening it in internet explorer as that seems to work better. Let me know how you get on.
