my daughter will wake up when she's hungry but If it's been over 4 hours I wake her up. she'll barely eat if I wake her up myself. do I let her sleep or continue to wake her up?

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...

I'm a FTM and trying to get my baby to sleep through the night. What are some tricks you ladies used? He will sleep from 10:30-2 but then wake up every hour to two hours after

When will baby sleep through the night? My daughter is almost 3 months and she is still waking up every 3 hours. 😩😴
