Accurately measuring infant milk intake during breastfeeding is
important in the management of hospitalized infants, as well as in
addressing breastfeeding concerns with healthy infants at home.
In the hospital, knowledge of milk intake improves clinical diagnosis
of feeding problems while providing essential information for precise
supplementation of infants at risk for under or over consumption1,2,3.
In the home, knowledge of milk intake ensures feeding adequacy and
enhances maternal satisfaction4,5.
Clinical indices of milk intake during breastfeeding, such as duration of
sucking, audible swallowing, and presence of maternal milk ejection,
are not accurate replacements for the evidence based practice of
test weighing before and after feeding. Using test weights may also
increase maternal satisfaction when compared to using clinical indices
to ensure adequate feeding5.

Determinar con exactitud la cantidad de leche que consume un
lactante durante el amamantamiento es importante no solo para
controlar a los bebés que están hospitalizados sino también para
abordar los problemas vinculados con la lactancia materna que tienen
los bebés sanos que se encuentran en el hogar.
En el hospital, saber cuál es el consumo de leche ayuda a obtener un
mejor diagnóstico clínico de los problemas de alimentación, además
de proporcionar información esencial para poder proveer el suplemento
alimenticio apropiado a los bebés que corren el riesgo de tener un
consumo por debajo o por encima del óptimo1, 2, 3.
En el hogar, saber cuál es el consumo de leche garantiza una
alimentación adecuada y aumenta la satisfacción de la madre4, 5.
Los índices clínicos respecto del consumo de leche durante el
amamantamiento, tales como el tiempo de succión, el ruido que el
bebé hace al tragar y la eyección de leche materna, no reemplazan
la exactitud empírica que implica controlar el peso del bebé antes y
después de alimentarlo. Además, es posible que este tipo de control
de peso aumente la satisfacción materna en comparación con el uso
de índices clínicos para garantizar una buena alimentación5.

La mesure précise de l’ingestion de lait maternel par le bébé pendant
l’allaitement est importante pour le traitement des nouveau-nés
hospitalisés, ainsi que pour répondre aux questions sur l’allaitement
dans le cas de nouveau-nés en bonne santé à la maison.
À l’hôpital, connaître la quantité de lait ingéré favorise un meilleur
diagnostic clinique des problèmes d’allaitement, et fournit également
des renseignements précieux pour supplémenter avec précision les
nouveau-nés à risque (sous-alimentés ou suralimentés)1,2,3.
À la maison, connaître la quantité de lait ingéré garantit un allaitement
adéquat : le contentement de la maman n’en sera que plus grand4,5.
Les indices cliniques d’ingestion de lait pendant l’allaitement, comme
la durée pendant laquelle le bébé suce, avale de manière audible,
et la présence d’éjection de lait maternel ne peuvent remplacer de
manière exacte la pratique fondée sur le pesage d’essai pendant et
après l’allaitement. Ces pesages augmentent également la satisfaction
maternelle, comparativement aux indices cliniques en vue de garantir
un allaitement adéquat5.

Explanation of Terminology
• Capacity (Maximum Capacity): This shows the
maximum weight that can be measured by the scale.
• Increment (Minimum Graduation): This shows the
interval of the numeric value change on the digital
display.
• Tare: The towel, blanket, etc., used when measuring
the infant weight is called “tare”. Measuring the infant
weight after subtracting the weight of the blanket is
called “tare weighing.”
• Pre-feed: Before feed or prior to feed.
• Post-feed: After feed or following feed.

• Do not use scale anywhere
that is subject to signi cant temperature change.
• Do not position scale anywhere that is either damp or
subject to high humidity.
• After positioning the scale and before use, pick up the baby
tray from both sides to con rm that the tray is secure, and
not easily removed.
• Ensure that the tray locking lever is pushed in.

19
