“…In an ideal world, perhaps children with risk factors about whom parents were concerned could receive intervention in the first year of life, and if they did, their developmental trajectories might be significantly altered in a positive direction. But EI is expensive (Hebbeler et al, 2009), SLPs are in short supply in many areas of the country ( U.S. Department of Labor, 2011), and the evidence that this scenario is valid is currently absent, as is the evidence as to what would constitute an efficacious treatment. Several research groups (summarized by Zwaigenbaum et al, 2009) studying the development of this population are experimenting with offering training to parents to maximize at-risk infants' opportunities for social-communicative development, but the results of this research have not yet been published.…”
