It is very challenging to try and find books for the early reader. Children are anxious to read but finding a book that will encourage success is difficult. Your child is just learning about short and long vowels and needs books with very simple text. I have found a site that offers books in very simple format that your child will be able to read using his/her knowledge of short and long vowels. Your child could either read them or the computer or you could print them out and keep them together in a bag that will allow your child easy access to them again and again.
