DD is 19 months old. She talks a lot, has been read to a lot and likes looking at books. In the last few days, she has started pointing to words (on her bottle, on a grocery list etc) and saying 'read it'. I have no wish at all to push her towards beginning to learn letters etc, but wonder what other people have done to respond to their child's interest in reading at this age. Some fun ideas for learning letters and/or words would be helpful.
