"There are some really tough words in my child's book. I am not sure of the word. What can I do?"
Some of the popular child's books have tough words. The author is trying to keep with a certain rhythm and rhyme and pick very advanced words. Don't worry. Go to google and search for the title and author of the book. Many times someone has a youtube video of them reading the book or a famous person has read the book. This is a great way to get the rhyme pattern of books like "Chica Chica Boom Boom" or the words of "Where the Wild Things are." The internet can be our friend.
