I started using Libby’s free audiobooks for myself before Mark was born. Libby is provided by the Singapore National Library. The books can be downloaded for 3 weeks and are returned automatically.You would never have to worry about a fine for overdue books. Since he was very young , I would let him listen whilst he plays and now he enjoys them so much we listen on long car drives and also when he gets his eye breaks from reading or doing homework-Dr Cheryl Lee
