Is it appropriate to use nursing room to express milk? As i felt/worried other breastfeed moms will think they should be the priority... sometimes felt so embarrassing when walking out of the nursing without carry any baby... ?

Some times the nursing rooms do say for shoppers with baby only. Anyway I ignore it when I need to pump. I figure they can't cater for every scenario when they wrote the sign. Some mummies do feel that pumping mummies need the room more as baby can nip. ( ok pumping also can but srsly never tried ) Not trying to start a war but I think there are differing POV. Generally agreed that pumping mums need the room as well ! Though it helps if they can see ur pump bag or big bag else they think real abuse case. Anyway I will just ignore cos it's a real need
