I actually think that some of our modern childcare devices may contribute to the reported increase in children “on the spectrum”. Years ago most babies were in mom’s arms, on mom’s hip, or in her lap. Mom’s warmth, breathing, and heartbeat were readily felt. Plastic baby carriers, while convenient for parents, create a disconnect. After 9 months of being and feeling part of the mother, today’s babies are deprived of that level of maternal closeness that once followed babies out of the womb and into the world.
