My baby is 1 wk. old and I've noticed that when I have let down my breasts will be sore during (this is even when she's not nursing). It's a throbbing pain that feels like engorgement (though they're not). Also once she is done nursing my nipple will turn white and the whole breast will be sore for a time. We've had to work really hard on latching, though it does seem to be getting better each time. I'm just wondering how long this pain should last or if there is something more I can do to fix it? Thanks!
