Someone mentioned a study from Australia being quoted by a formula company; Here it is....;Forster C.,Abraham S., Taylor A., Llewllyn-Jones D., "Psychological and Sexual Changes After the Cessation of Breast-Feeding" Obstet Gynecol 1994;84:872-6 "19 women completed the study.5 of the subjects became pregnant before weaning and ceased breastfeeding when pregnancy was confirmed; their last menstrual period was 6 weeks before weaning. The non pregnant women reported a significant decrease in fatigue, improvement in mood, and an increase in sexual activity, sexual feelings, and frequency of coitus. Significant changes in fatigue and mood occurred during the second week after weaning; in fatigue, sexual activity, and sexual intercourse during the third week; and in the frequency of sexual intercourse in the fourth week. The results were not caused by the subjects' expectations about breastfeeding and sexuality or perineal comfort. The women who conceived did not have these changes; a gradual increase in fatigue and decline in sexuality was observed." All the women in the study had been breastfeeding their first child for more than 6 months and were on no medication(including Oral contraceptives) This is a very small study. I don't believe it proves anything.Mothers with small babies are very focussed on their babies. This is a very important mechanism for survival of the species and probably has an evolutionary basis. What does everyone else think? Carolyn Lawlor-Smith LC/Dr. South Australia
