I used the lactation rooms at St. Marys when breastfeeding my oldest (now 3 yo). Relatively good experience, but most of the time I had to wait for a room or go to a different building to try and find an empty room. They never felt very clean and always had spilled milk and lunch remains from all of the use. I always brought disinfecting wipes and took some time to wipe down the pump, chair, table, etc. before I started pumping. I don't need to use a lactation room with my 2nd baby as I have a private office. I like the convenience of being able to pump whenever I want and not feel like I am wasting time locating an open lactation room, but I miss having a sink (not in a break room or bathroom) to wash my parts.
