What books are great to read for my baby girl who is already 6 months old?

Yes, I agree with Stan and Faye. There are books at bookstores for a specific age range. They are the colorful and 3D ones you see. You can also purchase a cloth book which is very ideal for babies 3 months onwards. Aside from telling them stories, they'll have a feel of different textures which is helpful to their motor skills and cognitive learning,
