Although Frances is seeing in color now, she still loves her book Black & White by Tana Hoban. The pages of this board book fold out so you can prop it up on the ground in front of her. The high contrast images capture her attention and hold it until she’s had her fill. Her favorite image at the moment is the butterfly.
My only complaint is that if these images are really “objects from your child’s ever-growing world”, then what’s sailboat doing in there. I wish all the images were things she’s familiar with at her current age, like maybe a crib instead of a chair. Or a hand instead of a fork.
Overall, I would recommend this as a first book for babies.
