Final answer:
The mother should keep the baby upright after feeding, gently clean the mouth and surgical site, and follow specific care guidelines provided by the medical team to ensure proper healing after cleft lip/palate repair.
Step-by-step explanation:
After feeding the baby who has had cleft lip/palate repair, the mother should ensure that the baby is upright to reduce the risk of liquid entering the nasal cavity due to the previous gap. This position helps in preventing choking and provides comfort to the baby. Additionally, the mother should gently clean the baby's mouth and surgical site according to the medical team's instructions to prevent infection and promote healing. Following the specific feeding and care guidelines provided by healthcare professionals is crucial for recovery and overall health after surgical repair of a cleft palate defect.
