The Problem

My mother-in-law got here today and I think she figured out what the problem is. Anna is not sucking hard enough on my breast. She kind of half-heartedly sucks, then falls asleep. Then wakes up ten minutes later, extremely hungry and mad. This development now makes sense as to why my milk refused to come in for eight days...

My MIL asked me if I felt a "whooshing" feeling while she was feeding, followed by her swallowing vigorously. Nope, never felt that.

So, how do you make a baby suck hard enough? How do you keep them awake, but not furious at you? Advice greatly appreciated.
