A client told me this week that when her daughter was born five weeks early and she did not have enough milk in the first week, the NICU nurse told her that since the baby had already recieved ABM that the baby could not have breastmilk because "mixing formula and breastmilk will upset the baby's digestive system and may make her sick". Amazing! I was incredulous.... and gave this mom credit for pumping anyways. And of course now we are dealing with a low milk supply and a premie who is nipple preferred to an artificial nipple.....I could strangle that nurse. Debbie Rabin, OTR, CLC Los Angeles, CA
