My 2.5-year-old daughter has a working diagnosis of autism. I’m finding it incredibly difficult to get my head around it. I do not want to sound unsympathetic, but how did this happen? Why are so many children being diagnosed with autism now? How much of this is a medical issue and how much of this is an environmental issue? My concern also is that if my daughter receives an autism diagnosis, how do I parent her? Popular culture has enough bad parenting advice, I wonder if the autism advice would be just as bad? I want my daughter to reach her full potential and autism not to be a label to excuse bad behaviors.
