Just out of interest, was hoping to pick other's brains. When I went back to work after dd, I expressed with a double electric pump for 6 months or so and have from day one had to use it a lot with ds due to weight gain issues. BFCs have looked at his/our(?!) latch and said it seems ok but I wondered if lots of expressing could have damaged or altered the nipples to make it hard for him to latch properly? Has anyone had any experiences?
