Not understanding sleeping or eating

My baby is 7 weeks old and she has difficulty sleeping. I read that one month olds are supposed to get about 14-16 hours, but she often stays awake for 6 hours straight or more. She only sleeps when she’s being held or during a feeding, then as soon as she gets placed in her bassinet or gets burped she wakes up. I try to get advice I see a lot of people mentioning wake windows, but I don’t really understand wake windows or what they are. Also, I worry that she eats too much because of how she falls asleep when eating. It’s hard to tell what else she needs when we put her down and she moves around or cries. I assume she’s just hungry after burping and changing her, I also try to make sure she’s comfortable with temperature and clothing and nothing hurts her.
