Can parenting style cause autism?
There is no scientific empirical support for the notion that mothers cause their children’s autism or that they lack reflective functioning and are insensitive to their children’s needs (Deslauriers, 1967; Keen, 2007). Indeed, it is widely accepted that mothers are not the cause of autism in children.
