Spacing babies less than 2 years apart may raise autism risk in second-born: study
No not sending them to space....although some may want to...
Children born less than two years after their siblings were considerably more likely to have an autism diagnosis compared to those born after at least three years.
The sooner the second child was conceived the greater the likelihood of that child later being diagnosed with autism. The effect was found for parents of all ages, decreasing the chance that it was older parents and not the birth spacing behind the higher risk.
