Breastfeeding help!

Baylee

I just had my baby at 34 weeks . She will be in the nicu for a week or so . I’ve been trying to pump for her ! But I’m not even being able to get enough colostrum for her 😩 I’m maybe getting a little over 1tbs . How can I help produce more !? I’ve been pumping every 3 hrs even tho I don’t get much . And I’ve been trying Nipple stimulation . she is only 3 days old but I want to help her !
