My daughter is 6 1/2 weeks old and I think was just going through a growth spurt. Alternate days of constant eating and lots of sleeping. She seems to be out of the spurt now, but I have been left with OS and major OALD. She is usually a calm eater, but now is writhing around, pulling off, and getting upset...when she pulls off, there is usually a strong stream of milk that continue to shoot out of my nipple for a long time, so I see why she is having a difficult time.
I am hesitant to block feed because I don't want to reduce my supply this early on. Nursing reclined helps sometimes but not always. I have used a hand pump for about a minute a few times too, but I am worried that doing that could exacerbate the problem in the long run.
