I have been gradually switching to formula for my dd over the past 6 weeks or so. The last time I b/f was 2 days ago. My right boob has still got some milk in - feels lumpy and slghtly uncomfortable. Do I just leave it, or express, or let dd feed off it to ease the engorgement ? Won't it then produce more milk ? My left boob is fine - she hasn't fed off that one for a week or so and I didn't have any problems with it. Any suggestions ?
