Impact of Measuring Milk Production by Test Weighing on Breastfeeding Confidence in Mothers of Term Infants.

AIM: The duration of exclusive breastfeeding is affected by maternal confidence and perception of milk supply, but objective measurement of milk supply is rarely used. Mothers of preterm infants have found measuring milk supply by in-home test weighing to be helpful to ascertain their infants' breastfeeding intake. This study aimed to determine if this technique affects breastfeeding confidence of mothers of term infants. MATERIALS AND METHODS: Participants filled in a survey of their breastfeeding confidence and perceptions of breastfeeding behavior prior to and after a 24-hour period of recording the times of feeds, amounts of each breastfeed or bottle feed (expressed breastmilk or formula), and amounts of breastmilk expressed. RESULTS: The breastfeeding confidence of at least 66% of mothers who were initially confident was maintained, and the breastfeeding confidence of at least 11% of mothers who were initially not confident was improved after objective measurement of milk supply and breastfeeding behavior. CONCLUSIONS: Measurement of actual milk supply and breastfeeding behavior provides objective information that can guide clinicians in the management of lactation. It can also help to maintain or improve breastfeeding confidence.

Frenulotomy for breastfeeding infants with ankyloglossia: effect on milk removal and sucking mechanism as imaged by ultrasound.

OBJECTIVE: There is evidence that infants with ankyloglossia can experience breastfeeding difficulties including poor attachment to the breast, suboptimal weight gain, and maternal nipple pain, which may lead to early weaning of the infant. No studies have investigated the cause of these breastfeeding difficulties. The objective of this study was to determine the effectiveness of frenulotomy in infants experiencing persistent breastfeeding difficulties despite professional assistance by measuring changes in milk transfer and tongue movement during breastfeeding before and after frenulotomy. PATIENTS AND METHODS: Twenty-four mother-infant dyads (infant age: 33 +/- 28 days) that were experiencing persistent breastfeeding difficulties despite receiving professional advice were recruited. Submental ultrasound scans (Acuson XP10) of the oral cavity were performed both before and >or=7 days after frenulotomy. Milk transfer, pain, and LATCH (latch, audible swallowing, type of nipple, comfort, and hold) scores were recorded before and after frenulotomy. Infant milk intake was measured by using the test-weigh method. RESULTS: For all of the infants, milk intake, milk-transfer rate, LATCH score, and maternal pain scores improved significantly postfrenulotomy. Two groups of infants were identified on ultrasound. One group compressed the tip of the nipple, and the other compressed the base of the nipple with the tongue. These features either resolved or lessened in all except 1 infant after frenulotomy. CONCLUSIONS: Infants with ankyloglossia experiencing persistent breastfeeding difficulties showed less compression of the nipple by the tongue postfrenulotomy, which was associated with improved breastfeeding defined as better attachment, increased milk transfer, and less maternal pain. In the assessment of breastfeeding difficulties, ankyloglossia should be considered as a potential cause.
