I thought I had posted this study URL to Lactnet when I found it, but doing an archive search I could not verify it. Periods returning early as 6 weeks are not due to pacifier use or no nighttime breastfeedings but predicted by measurable hormone levels at 38 weeks in pregnancy. This happened to my daughter who made valiant efforts to feed at night and did not ever give a pacifier. It may be hereditary as child spacing of her paternal grandmother was close--4 children birthed in 3 years even while breastfeeding. Judy Ritchie CONCLUSION: At 38 weeks gestation, the ratio PRL/oestradiol identified all individual women according to the subsequent duration of their lactational amenorrhoea, suggesting that duration of lactational amenorrhoea is conditioned during pregnancy. http://humrep.oxfordjournals.org/cgi/content/full/16/12/2540 *********************************************** To temporarily stop your subscription: set lactnet nomail To start it again: set lactnet mail (or digest) To unsubscribe: unsubscribe lactnet All commands go to [log in to unmask] The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(R) mailer for lightning fast mail delivery.
