Final answer:
Soother/pacifier use should be avoided when establishing breastfeeding to prevent nipple confusion and support an effective latch-on technique. Instead, utilize skin-to-skin contact, rocking and carrying, and frequent breastfeeding to encourage bonding and breastfeeding success.
Step-by-step explanation:
The method of soothing that should NOT be utilized when an infant is establishing breastfeeding is soother/pacifier use. This is because early use of a pacifier may cause nipple confusion and interfere with the establishment of an effective latch-on technique during breastfeeding, which can lead to less effective feeding and potential breastfeeding problems. Instead, methods such as skin-to-skin contact, rocking and carrying, and frequent breastfeeding are encouraged as they promote bonding, help regulate the baby's heartbeat and temperature, and support breastfeeding success.
