I have a 13 month old who is still babbling, and turned to this book for direction with her language development. While I found some of the information interesting, it is mostly a compilation and description of all of the relevant research associated with language development. There were a lot of examples and (unnecessary) visual aids, but nothing that really gave me the insight I was looking for (i.e. how to aid her in attaining this milestone). Basically, they proved that there is nothing specific one can do and that children will begin talking when they are ready. I wish I had simply read the summary first, as it would have saved me a lot of time!
