What are some engaging books for a 5-month-old?

At this age, babies respond best to books with bright, bold illustrations and very little text. Classics like 'The Very Hungry Caterpillar,' 'Brown Bear, Brown Bear, What Do You See?', and 'Goodnight Moon' are favorites. To make reading engaging, use a sing-song, animated voice to keep their attention, and don't worry if they just want to explore the book with their hands or mouth.
