New mom needing help with feeding?

baby is 9 days old. Baby wants to nurse very frequently, and for a short amount of time, and then usually falls off to sleep. I try to awaken her with wipes and such but it usually doesn't work to try and get her to eat more at a time. She awakens also usually very soon after I put her down. Some feedings may be five minutes and then 30 minutes or so or an hour later she wants more. Am I doing something to cause this problem with the short feedings? She won't sleep very much at a time either? Please help
