A dog, wuf-wuf. A whole book or a magazine may take only minutes to read. At first this may be as long as your child will stay with you. When your child cannot keep seated any longer, end the session without scolding or reprimanding the child. Frequently children want the same book read over and over.
Repetition is one of the ways they learn.
When your child can sit through several minutes of looking at a book, try asking her to point to a picture you name. If she points to it make a big fuss, maybe clap. Your child will slowly get the idea. Eventually, you will be able to ask your child to tell you the name of something you point to. This activity should be a nice experience for both the parent and the child.
