• Illness.
• Pain.

• Poor breastfeeding technique: possible causes:
  
• Feeding from a bottle or suckling on a pacifier.
• Not getting enough milk because of poor attachment.
• Mother holding and shaking the breast interferes with attachment.
• Restricting breastfeeding (e.g., breastfeeding only at certain times).
• Too much milk coming too fast because of oversupply.
• Early difficulties in coordinating suckling (some infants take longer than others to learn how to suckle effectively) − Infant refusing one breast but not the other.
