From the time Braden was born he has been the owner of quite a fine library. I wouldn't say proud owner because he has been way too busy for books most of his life. Arica and I were determined to read to our son so we bought books all the time. We encouraged the grandparents to buy books. We wanted books.
As time went on Braden wouldn't even let us read him a book. If we tried he would just take it away. Getting through one page was quite an accomplishment.
Eventually that led to him "reading" books himself. He would take them from us, but at least he would look at them for a few moments. After that you would sometimes find him sitting in the floor of his room surrounded by a pile of books.
We have one low bookshelf that is just above the floor. He can easily get those books and read them. He would look at one, throw it down, and get another. This would continue until they were all on the floor. He still does that.
A little while later Arica and I stored some of his toys and clothes in big plastic tubs. I was slow in getting them stored under the house so the tubs sat in Braden's room for a few months. During this time Braden started climbing up on one of the tubs so he could reach the books on top of his big book shelf.
