Yay! What terrific progress!
Yesterday I was able to get a total of 6 oz, which has been an increase from 3/4 when I started. I know have been bf with the shield and today was able to get her to latch on without the shield one time (figure if she did it once, she can do it again).
Maybe what's happening is that your baby is taking more milk from the breast now, leaving you with less to pump out?
My milk supply is down today, not sure why. But I have been attempting to bf, then supplement with formula and then pump.
