Dear Friends: I too am interested in any information about bf and autism. Here is one study: J Autism Dev Disord 1989 Sep;19(3):425-34 Weaning time of children with infantile autism. Tanoue Y, Oda S Department of Clinical Psychiatry, Yuhara Hospital, Ibaraki, Japan. Since early weaning in infancy has been known to result in vulnerability to infection, weaning times of 145 children diagnosed as autistic by DSM-III were statistically compared with those of 224 normal children in the same catchment area: 24.8% of the patients and 7.5% of the controls were weaned by the end of 1 week, a significant difference. Early weaning because of the mother's rather than the child's condition occurred with 17.9% of the patients and 5.8% of the controls, also a significant difference. Historical studies on infantile autism revealed that the disease developed more prevalently in the socioeconomic status where the incidence of breast-feeding was less frequent. These results suggest that early weaning may contribute to the etiology of infantile autism.
