By doing this you allow reading to occur spontaneously. Put an accessible bookshelf in your child's room to make a library corner with very little space. The shelf can be as simple as some cinder blocks and pieces of wood placed low at the child's level. Adding a cushion or special chair can make this a private reading spot for your child. Put books in the toy box or wherever you keep toys.
Children spend a lot of time in both the kitchen and the bathroom.
Put books there. The key is to put books wherever they can be visible and accessible. This increases the likelihood that the books will be picked up and used. Babies can have books in their cribs and play pens. Use waterproof books in the bathtub.
