How much breast milk each pumping session should one be able to get at 18 months?

My baby is 18 months old and I still bf her and pump . How much milk in oz does a well established bf mom usually pump per session , that bf 5 times per day? Please someone respond that either has experienced this or knows someone who has. thanks!!!|||I am still breastfeeding my 10 month old up to 10 times a day and am lucky to get 2oz per pumping session. I think it really depends on how good you are at pumping.|||I usually only get 1-2 oz per session, that is pretty normal. It is difficult to get more than that when pumping, although baby can get more.
