Some random questions

My baby it over 7 days old and I feel like me/my breasts are still not doing the good job they're suppose to.

I've only had the let down effect happen twice, a few days ago while pumping. Should I have it all the time?

I'm still only able to pump 1.5oz with both breasts combined. Should I have more?

Occasionally my entire nipple area feels heavy after feedings. That a good sign?

My right nipple still has a burning sensation with each feeding. But shows no other "injury" like cracked or bleeding. But is our latch with that one not good?

The yellow seeded poop seems to be after each diaper. Why so often?

(Some of these questions I have to wait until office hours to call and ask)
