DD1 loves when we read to her and she has a vast vocab for her age (not all clear but words all the same), i have found the books with colors and the lift-tabs are brilliant, she will copy when we say PINK then she says PINK ICE CREAM or PINK FLOWER.

I go to the discount book stores and she often 'picks' a book, sometimes it's just full of gorgeous pictures, other times it's something she recognises.

I find books she recognises a picture in more fun for her, she relates and gets excited as we flip the pages.
Some of her books are quite long and detailed but she will sit there and just enjoys pointing at the pictures she knows and listening to the sound of my voice.

Good luck choosing.. Dr Seuss are good.
