I have a Sept. 2005 baby and he also isn't talking well. Unlike your dd he doesn't point to anything in a book. Kaden quilified for speech therapy. The therapist gave me these things to do with him, which like you I have already been doing.
*read books to your child frequently.
*talk simply, clearly, and slowly to your child.
*enjoy many activities w/ your child to stimulate language,
vocabulary, and communication skills-take walks, go shopping, have a picnic, clean house, plant flowers, and talk about things as you are doing them and again later in the day.
*look at your child when he or she talks to you
*describe what your child is doing, feeling, and hearing in short 3-word sentences
*make speaking and listening experiences pleasant, worthwhile, and fun for your child
*let the child listen to children's music and book recordings
*respond to your child's attempts at communication in a meaningful way.
