Katherine: What kind of supportive literature are you looking for? Literature that shows introduction of artificial nipples will undermine breastfeeding? Literature that encourages rooming-in? As far as stuffing cotton into a bottle nipple to be used as a pacifier, I don't think we'll find research on that because it's using a product for something other than its intended use. You might just suggest the issue of product liability. (People in hospitals tend to hate the "L" word.) I found these references in the ASPO/Lamaze Position Paper on Infant Feeding which reprinted information taken from the ILCA 1995 Position Paper. Salariya EM, Easton PM, Cater JI: Duration of breast-feeding after early initiation and frequent feeding. Lancet 2:1141-43, 1978. Keefe MR: The impact of infant rooming-in on maternal sleep at night. JOGNN 17:122-26, 1988. Norr KF, Roberts JE, Feese U: Early postpartum rooming-in and maternal attachment behaviors in a group of medically indigent primiparas. J Nurs Midwif 34:85-91, 1989. Yamauchi Y, Yamanouchi I: The relationship between rooming in/not rooming-in and breast-feeding variables. Acta Paediatr Scand 79:1017-22, 1990. Waldenstrom U, Swenson A: Rooming-in at night in the post-partum ward. Midwifery 7:82-89, 1991. Victora CG, Tomasi E., Olinto MTA, et al: Use of pacifiers and breastfeeding duration. Lancet 341(8842); 404-6, 1993. Newman J: Breastfeeding problems associated witht he early introduction of bottles and pacifiers. J Hum Lact 6:59-63, 1990. Anderson GC McBride MR, Dahm J. Et al: Development of sucking in term infants from birth to four hours postbirth. Res Nurs Health 5:21-27, 1982. There are probably others I'm overlooking. Any other favorites out there?
