need some advice

I had my baby Monday and she is ebf since I've had her she has done great as far as nursing goes but today she hasn't wanted to stop at all total time I've spent nursing is 6 hours with maybe a 10 minute break in between I feel like she's using me as a pacifier but she won't take a binky and everytime I nurse she falls asleep after maybe 2 minutes as soon as I unlatch her she starts fussing and rooting I'm definitely producing..idk what's going on I didn't have this problem with my first except for the first 3 days waiting for my milk to come in any and all advice is appreciated
