I need help!

Breastfeeding is so much harder than I expected! After nursing, 99% of the time, ds still acts hungry. This is after pushing my breast away. I try to get him to latch again but he refuses. A few minutes later he starts gnawing on his hands. He is also pretty fussy throughout the day.

He's 1 month old (today). Weighed 9#7oz at birth and 12lbs now. So I know he's gaining. He's having plenty of wet and poopy dipes.

I'm about ready to quit bfing.

What do I do? Is he hungry?
