BALONEY! If she is getting painfully engorged she needs to pump or feed baby. It isn't the "o" that causes it but sexual stimulation does cause the breasts to fill up because the body can't differentiate between baby's touch and spouse's touch. I nursed my babies for a looooooooong time and so did most of my friends and NEVER has nursing been used as a reason not to o. This is pure fabrication. I'm sorry that she has convinced herself of such a silly thing.
