ASD Parenting Ideas to Change. 

"Parents, especially those of special-needs children, will sympathize with Christiansen’s fight for the acceptance of her child’s—and by extension all children’s—differences."

Follow the journey of mother and son as they navigate the twists and turns of autism spectrum disorder. This memoir, spanning the years from diagnosis through middle school, gives the reader an inside view of high functioning ASD, the view that many teachers, family and friends may never see. Planet A is a book of stories, stories that show the struggles and celebrations of autism. Its pages are designed to give the typical world a window into our planet and to let those already living on planet autism know that they are not alone.​​​​​​
