This is a suuuuper cute toy, our grandson loved it, but he is almost 18 months now & has waaaay too many toys. as you can see, each page of the hard plastic 'book' has a different animal and as baby turns each page the coinciding page makes that animal sound, electronically, it has new batteries too. the buttons make music, and this toy reeeeally keeps baby engaged. what baby doesn't like phones, buttons, and engaging animal sounds ...all the bells & whistles on this one!!!
