Is it ok to let your baby use your breast as a pacifier?

Tough question: The infrequent use of nursing for comfort during painful procedures or other distress can be helpful. Frequent pacifying with this method can result in undesirable attachment issues and impair the development of self soothing tactics (your baby may not be able to fall or stay asleep unless nursing). This habit can be VERY distressing for you both later when you wish to stop.

Yes: Many women who breast feed do. I know a lot who continue to breast feed at bedtime to help get the baby to sleep even after they are eatting other foods at mealtime. However, you should beware of doing this after the baby has teeth. Bites can hurt and can get infected.

Pacifier: There will be lots of differing views on this and not one answer is right or wrong. All personal decisions. I'm personally not in favor of it. There are lots of other ways to soothe a baby. For your own sanity, you kinda want to keep the breast just for feeding. IMO

Odd question: Breast feeding is a combination of nutrition and nurturing. Some babies are wired to need more nurturing than others, some are "gourmet" feeders and linger at the breast, seemingly playing with their feed. No one can know your baby better than you, so you need to decide if baby is looking for nurturing, or your just using the breast to stop fussy periods,that could just be fatigue.
