It may already be controlled for, but if not, the increased Acetaminophen intake could be from narcotic painkillers, which are often combined with Acetaminophen in prescription preparations to help prevent abuse. The same people seeking and using those around birth may later seek to get an ADHD diagnosis for a child for access to amphetamines, as narcotics use and amphetamine use are highly correlated together.
