Breast shields can be beneficial for both mothers and babies in several scenarios: - Protection for Sore or Cracked Nipples: Shields help protect sensitive areas while still allowing breastfeeding to continue. - Latch Difficulties: In cases where a baby struggles to latch on correctly, a breast shield can help facilitate a better latch. - Flat or Inverted Nipples: Mothers with flat or inverted nipples may find that shields make breastfeeding easier.
