Truth #2 The best way to increase milk supply is to directly feed or express milk. Establishing milk supply • Skin-to-skin immediately after birth • Latch within the first hour • “Empty” breasts at least 8-12 times daily Baby tracking app, SmallNest, reported that on average, parents of 2,000 U.S. and Canadian babies reported 16-18 feeds per 24 hours ABM clinical protocol #5: peripartum breastfeeding management for the healthy mother and infant at term, revision 2013. Breastfeeding Medicine. Vol. 8, No. 6, 2013. URL: https://www.bfmed.org/protocols Increasing milk supply • Assess latch and transfer • Continue to drain breasts, including overnight when prolactin is highest • Medications: metoclopramide, domperidone (not FDA approved) • Hydrate and eat to thirst/hunger • Limited evidence for herbs and supplements ABM clinical protocol #9: use of galactogogues in initiating or augmenting maternal milk production, second revision 2018.

Truth #4 There is often no need to “pump & dump” for anesthesia, imaging, alcohol, or medications. Anesthesia Wanderer et al. Anesthesia & Breastfeeding: More Often Than Not, They Are Compatible. Infographic. Anesthesiology: October 2017, Vol.127, A15. Imaging • Radiographic studies do not make milk radioactive! • Mammograms can be done, although with decreased sensitivity. Best done immediately after draining breasts. • Per American College of Radiology, it is safe to continue breastfeeding after iodinated or gadolinium-based contrast agents. Manual on Contrast Media. American College of Radiology. Version 10.3, 2018. URL: https://www.acr.org/- /media/ACR/Files/Clinical-Resources/Contrast_Media.pdf American College of Radiology “Because of the very small percentage of iodinated or gadolinium-based contrast medium that is excreted into the breast milk and absorbed by the infant’s gut, we believe that the available data suggest that it is safe for the mother and infant to continue breast- feeding after receiving such an agent… [If the mother chooses to “pump & dump,”] There is no value to stop breast feeding beyond 24 hours.” Manual on Contrast Media. American College of Radiology. Version 10.3, 2018. URL: https://www.acr.org/- /media/ACR/Files/Clinical-Resources/Contrast_Media.pdf Alcohol in Breast Milk • Alcohol is found in the breast milk in approximately the same concentration as in the blood, and similarly leaves the breast milk as it is metabolized by the mother • Legal limit to drive 0.08%=percent alcohol in breast milk at legal limit • Percent alcohol in apple juice: 0.06-0.66% • Percent alcohol in non-alcoholic beer: <0.5% Gorges et al. Estimates of Ethanol Exposure in Children from Food not Labeled as Alcohol-Containing. J Anal Toxicol. 2016 Sep; 40(7): 537–542. Alcohol in Breast Milk • Highest concentration at 30- 60 min. after drinking • On average, one drink is metabolized completely in 2 hours (nomogram by Motherisk: https://www.ncbi.nlm.nih.gov/p mc/articles/PMC2213923/pdf/1 1852608.pdf) Alcohol in Breast Milk • Thomas Hale (2017): “…mothers who ingest alcohol in moderate amounts can generally return to breastfeeding as soon as they feel neurologically normal.” • Alcohol does decrease oxytocin release and therefore inhibit let-down reflex and production • Studies have shown that weight, linear growth, and psychomotor development can be affected by moderate drinking in breastfeeding mothers Hale, Thomas.

Myth #5 It is generally safe to breastfeed in low-risk pregnancies. Breastfeeding during pregnancy • Nipple stimulation does release oxytocin, but in a similar or lesser amount than with sexual activity • Oxytocin receptors are sparse until 38 weeks and are also blocked by progesterone • Only a few small observational studies have been done, but there is no evidence to suggest an increase in miscarriage or preterm delivery Flower, Hilary.

If the pregnancy is normal and the mother is healthy, breastfeeding during pregnancy is the woman’s personal decision. If the child is younger than two years, the child is at increased risk of illness if weaned.” Breastfeeding, Family Physicians Supporting (Position Paper).
