Breast feeding

My baby girl is only a week old. I'll feed her and she will fall asleep I burp her change her diaper let her eat more till she falls asleep again then I lay her down. The second I lay her down she starts fussing and shows cues of being hungry again! I feed her again till she falls asleep and try to put her back then she does the same thing. I'm so tired and boobs need more then a 2 second break. Has any mom's have this problem before? What should I do? She's latching properly I seen a LC who taught me how to latch in the hospital but my baby wasn't doing this in the hospital
