I really enjoy reading lots of books to the kids. I do think it increases their vocabulary immensely, but it make me SO tired when I do it in the late afternoon. I wish there was a way to have two mornings each day.
SO Can you have too many books? We have stacks next to our beds (in every room), book shelves in every room in the house (well the kitchen technically doesn't have a shelf, but I have a whole cabinet of cookbooks in there). I really enjoy coming across a stack of books that the kids have put together for their own reading. It makes me think that I should read some more.
