My 8 week old has been refusing to breastfeed during the day for the last week... It's driving me crazy. She cries and cries and cries... Her diaper is clean and dry, I try to burp her, I try to calm... But nope... And I know she's hungry because she's putting her fists in her mouth. At night she's feeding well, around 3-4 times. I don't know what else to do .... After 20 min of crying she eats... Helppppp
