Agreed. Please provide this study.
While you're at it, compare and contrast it with the the thousand other studies that show a link between autism and gestational diabetes, antidepressant use, maternal allergies, neonatal and infant autoimmune processes, neonate and infant GI disturbance, latent herpes infection, maternal illness, neonatal and infant exposure to televised stimuli/interaction, maternal spotting, parental obesity, second-hand nicotine exposure, fetal hypoxia, low fetal birth weight, early gestational period, perinatal or neonatal ingestion of flavonoids in food, maternal thyroid variances, exposures to mercury or lead, and lastly
that ignorant, yet persisting theory of vaccines (despite incredible evidence).
See? I, too, can espouse theories I've read without providing peer-reviewed data.
