What would you do?

I’m 30 weeks pregnant with my twin boys. & my girl is still nursing in the morning & at night. In the morning she nurses on my left side & usually for a really really long time, the other day it was for an hour. I got my new Elvie pump today so I decided to try it out. I didn’t even get an ounce out, & I did my right boob the one she hasn’t touched yet today. & it’s colostrum. I’m wondering if I should just stop “nursing” her since she’s not even getting anything, she’s just doing it for comfort. I knew I didn’t have a lot of milk but I for sure thought I would have more if she’s nursing for so long each time.

What would you do? Keep doing it? Cut her off? I love nursing her but I was planning to stop before the boys get here anyway.
