Macy's at Hilldale Mall has an area where moms who want more privacy to breastfeed can use. Everyone entering the rest room goes through this area. A pleasant, carpeted lounge with several chairs and a sofa. Several small tables. Door is usually propped open, but can be closed (but not locked) for more privacy.
Of course moms are also legally allowed to breastfeed anywhere within the mall they feel comfortable under Wisconsin breastfeeding law.
