Investigating for Low Milk Supply Objectives Recognizing When Things are 1. Differentiate the three main categories of milk production problems. 2. List at least 3 risk factors for lactation problems in the early postpartum 3. Relate the importance of current pregnancy history to lactation capability 4. Explain the impact of infant suck on What’s going on? maternal milk production Lisa Marasco MA, IBCLC, FILCA [email protected] © 2019 ~No disclosures~ Are things Gathering good clues Start by listening to mom’s story heading south? Is there really a problem? No Reassure, educate Yes Take a detailed history Risk factors for delays Breastfeeding Management Yes Further Observations Infant assessment Well, it’s all Feeding assessment about the clues Maternal Assessment Differentiate delayed, primary and/or secondary causes Early weight loss Start Here → Is baby getting enough? >7%? >10%? Vag Lots of smaller stools OR Delivery Less often but blow-outs C-sect Once milk comes in, baby Delivery should start to gain 30- 45g/day in the first 1-2 mo Flaherman, et al. (2015).

Low milk supply and the pediatrician. Month 4 Gains 4-6 oz (120-180g) per week Curr Opin Pediatr.

Fast, slow, on target? Oz Formula? Is it Mom or is it Baby? If things really are heading south… Is baby not getting enough because mom isn’t making enough? #1: Feed the Baby Or is there enough milk but baby can’t get enough out? #2: Protect/Work on Supply Or was there enough milk but now there isn’t because baby killed off the supply? #3: Find the problem © Lisa Marasco 2019 2 Investigating for Low Milk Supply First fork in the road DELAYED ONSET: Milk in >72hrs (noticeable fullness) Happens to over 1/3 of mothers in U.S. studies!

How well did baby do her job? The Magic Number Pumping Equipment Mom may own the equipment, but… The Baby Drives the Supply Baby’s early feeding experiences at the breast factor into long-term production Has baby been latching well and often from the start? Baby’s early feeding experiences at the breast factor into long-term production Infant & Feeding Assessment Infant birth and health history Physical assessment Suck assessment How does mother describe baby’s feeding behavior in relation to available milk supply? Observe a feed and/or test-weighing Look What do you see and hear Consider that a problem may be multi- and when baby factorial tries to latch Listen & suck? © Lisa Marasco 2019 6 Investigating for Low Milk Supply What do we know about baby? Infant suck affects prolactin surges Zhang et al. (2016). Are Prolactin Levels Linked to Suction Pressure? Low suction pressure High infant birth weight Smaller than average surge Shorter gestational age Because it’s all about suck High maternal pre-gestational BMI Prolactin surges affect the lactation Infant suck affects milk removal curve Baseline a product of surges Poor milk removal → Influenced by frequency Residual milk → & quality of stimulation Lower persistency → PRL clearance = 180 min; Decreased milk 200-400 ng/mL >8x sustains elevation (Cox 1996) production 60-110ng/mL “Cows with a higher percentage of residual milk usually have a lower Pregnancy persistency of lactation” 8-20 ng/mL Non-lactating - Hurley 2010 Preg 0 3mo 6mo BIRTH 1 mo 2 mo 3mo 4mo 5mo 6 mo 9mo Red Flags Suck Problems: Jaw Difficult birth Receding chin (retrognathia) Livingstone, 2000 © Lisa Marasco 2019 7 Investigating for Low Milk Supply Less Common Infant Issues Soft palate cleft Cleft of Lip & hard palate Submucosal Cleft Bifid uvula Bifid uvula Photo by Catherine Watson-Genna Borderline early & premature Fatiguing The Sleepy / Lethargic / Worn Out Baby Typically symptomatic of poor milk flow May also indicate infant stress from poor muscle tone Heart problems All can inhibition of tongue mobility affect suck! infection Central Nervous System problems The self-limiting feeder Low muscle tone Photo courtesy of Diana West © Lisa Marasco 2019 8 Investigating for Low Milk Supply Red Flags Frequent choking, sputtering & pulling away Airway: Strategy for airway issues Laryngomalacia Remember that air wins over food every time Inspiratory stridor due to -Cradle hold can make it worse- prolapse of walls in larynx facilitate latching upright, with during inhalation head extension May worsen over the first few months, but usually -Paced feeding (breast/bottle) resolves by 2 yrs -Time for physiological maturation
