Warning signs <strong>of</strong> ineffective breastfeeding<br />

What are the warning signs <strong>of</strong> ineffective breastfeeding in the infant? For example, if milk production is<br />

inadequate secondary to poor latch-on or infrequent breastfeeding, the infant may become dehydrated<br />

with a concurrent increase in his or her sodium level. Prolonged hyperbilirubinemia may accompany<br />

the dehydration. Dehydration occurs over days to weeks, depending on the milk supply and the<br />

frequency <strong>of</strong> breastfeeding. In rare cases, the sodium concentration may be as high as 180 mmol/L.<br />

Nothing may be inherently wrong with the mother's milk, but if it is not adequately removed from her<br />

breasts, either by suckling or by pumping, the milk becomes weaning milk with a higher sodium<br />

concentration.<br />

The main reason that the sodium level increases in the infant, however, is volume contraction<br />

secondary to dehydration and insufficient water in the milk. Human milk is 87% water, but its<br />

composition changes if an insufficient amount <strong>of</strong> milk is removed from the breast. The treatment <strong>of</strong> an<br />

infant with hypernatremic dehydration is to replace the free water losses slowly, because an abrupt<br />

decrease in the sodium level can trigger seizures secondary to cerebral edema and the rapid flux <strong>of</strong><br />

sodium concentrations. This treatment involves giving the infant intravenous fluid with decremental<br />

concentrations <strong>of</strong> sodium to achieve a normal serum sodium level.<br />

Another warning sign <strong>of</strong> ineffective breastfeeding is failure to thrive in the breastfeeding infant, which<br />

also results from an insufficient milk supply. An infant can have both hypernatremic dehydration and<br />

failure to thrive. These disorders occur along a spectrum depending on whether the milk produced is<br />

adequate to maintain the infant's hydration state but insufficient to allow adequate growth. The primary<br />

care provider must assess the growth <strong>of</strong> the breastfeeding infant over time. Neonates typically regain<br />

their birth weight by 2 weeks <strong>of</strong> age, and their weight should increase by 50% at age 6-8 weeks. At 4-5<br />

months <strong>of</strong> age, the baby's weight should be double his or her birth weight. Also, the infant's head<br />

circumference and length should be assessed. The monitoring <strong>of</strong> subcutaneous fat deposition also<br />

aids the clinician in assessing the adequacy <strong>of</strong> growth. An infant's growth should follow the growth<br />

curve.<br />

Failure to thrive in an infant should not be attributed to breastfeeding without an exploration <strong>of</strong> other<br />

differential diagnoses. The mother whose infant is failing to thrive should be encouraged to breastfeed<br />

with close assistance and, possibly, short-term supplementation. Daily visits for weight checks and<br />

overall health assessments are <strong>of</strong>ten necessary. In rare cases, hospitalization may be indicated.<br />

ASSESSMENT OF THE NEONATE Section 7 <strong>of</strong> 11<br />

General principles<br />

The assessment <strong>of</strong> the breastfed infant includes an evaluation <strong>of</strong> its voiding and elimination patterns;<br />

feeding routines; jaundice; and, most importantly, weight. In addition, the mother should be examined<br />

for pain or irritation <strong>of</strong> her breast and nipples and for signs and symptoms <strong>of</strong> undue stress or fatigue.<br />

Healthy breastfed neonates should not lose more than 10% <strong>of</strong> their birth weight, and they should<br />

regain birth weight by the time they are aged 10-14 days. Newborns should have a minimum average<br />

weight gain <strong>of</strong> 20 g/d between ages 14 and 42 days. The average weight gain during this time is 34<br />

g/d for girls and 40 g/d for boys. In addition, breastfed neonates tend to gain weight faster than<br />

formula-fed neonates for the first 2-3 months, and the rate begins to slow at 6-12 months. Breastfed<br />

infants also tend to have leaner bodies than those <strong>of</strong> formula-fed infants.<br />

In the first 48 hours after birth, the neonate may void as infrequently as a couple times a day. Once<br />

the mother's milk supply is established, the baby voids after most feedings, usually 6-8 times a day.
