my little one just finished her 2nd full day of nursing. She is starting to get the hang of it and my nipples are extremely tender. She likes to nurse for a loooooong time. I'm talking an hour on one breast! My milk hasn't even fully come in yet so I don't understand how she can nurse for so long. Is she just using it more as a soothing suck? Should I just continue to allow her to suck for over an hour on one side?
