Gloria is labeling the objects in the book, which is a way of supporting her son's language development by teaching him the names of things. Recasting involves restating what a child says in a corrected form, echoing involves repeating what a child says, and motherese involves using a simplified form of language when speaking to a young child. While these strategies can also be helpful for supporting language development, they are not being used in the scenario described.
