Waking to feed?

My dd is a week old and I was told by her doctor to wake her every 2 hours during the day and 3-4 hours at night to feed her. For the first 3 days I did that and when I would wake her fit a night feeding she was fussy and usually wouldn't go back to sleep and would want to nurse constantly until about 9 am. I tried not waking her last night and she slept beautifully! She woke up around 6 hours in and ate then slept another hour or so and ate again. Is it ok to let her sleep?

So my baby is 8 weeks old and is thriving with weight gain each doctors visit. So here is my question: around 4-5 hours at night for sleep she wakes up every night and sucks on her thumb. (She finally this week likes it to soothe her during nap times) her eyes are still closed and she moves around and sucks it. I wake her to feed her. My question is should I just let it go? And see if she is just soothing herself to sleep? I don't want her to stave by morning if she sleep a couple of more hours...

Opinions on hungrier baby milk? My girl is drinking well over 30 oz in 24 hours. I tried her with water inbetween feeds but she just won't settle in till she has milk as she's hungry not thirsty. She's awake like 18 hours a day 😭

my child stays awake most of the day and literally sleeps only an hour to an hour and a half during the night...is there a way I could do something to make her sleep a little longer? I hear about peoples newborns and babies sleeping 4 to 5 hours, but mine wont shes fought it since I had her
