✍️ Sample CBS Questions & Answers
1. What is an effective way to support a mother struggling with breastfeeding?
When a mother struggles with breastfeeding, providing empathetic emotional support validates her feelings and reduces stress. Hands-on guidance from a lactation consultant or trained healthcare professional can help identify and correct latch or positioning issues, offering practical solutions and building her confidence to continue breastfeeding.
2. A mother at 3 weeks postpartum reports her breasts feel soft and no longer engorged. She worries her milk supply has dropped. What is the most appropriate response?
Breast softening around 3-6 weeks postpartum indicates milk supply has regulated to match the baby's needs, not that supply has decreased.
3. A mother asks whether she should wake her sleepy newborn for night feedings. What is the best guidance?
Newborns need frequent feedings to establish supply and prevent excessive weight loss; most should not go longer than 2–3 hours between feeds until birth weight is regained.
4. A mother reports her milk 'never came in' after her previous child was born at 30 weeks gestation and stayed in the NICU. For the current pregnancy, the CBS should document this history to:
Previous lactation difficulties, especially with a premature infant, guide proactive support planning to prevent recurrence in the current lactation journey.
5. A mother calls a crisis line stating her infant has ingested breast milk she accidentally expressed after consuming a large amount of alcohol 2 hours prior. What guidance applies?
Alcohol does transfer to breast milk in proportion to maternal blood alcohol levels; a single exposure warrants monitoring for sedation but is rarely an emergency unless the mother was severely intoxicated.
6. A CBS notes in the chart that a mother has bilateral breast hypoplasia with wide intramammary spacing. This finding is documented because it:
Wide intramammary spacing and hypoplastic breasts are physical markers associated with insufficient glandular tissue (IGT), raising risk for low milk supply.
