Firstly, it is essential to prevent the accumulation of milk and avoid damage to the nipples while keeping them clean. After each breastfeeding, wash the nipples with soap. If the nipples are inverted, frequently squeeze and pull them to correct this. It is important to establish a regular breastfeeding schedule to prevent the baby from sleeping without releasing the nipple. Each breastfeeding session should drain the milk completely; if there is any accumulation, massage or use a breast pump to extract all the milk. After breastfeeding, clean the nipples. If there is any damage or cracking on the nipples, timely treatment is necessary. For the care of the baby's oral cavity, local heat application and massage can be provided.
