4 day old...feeding pattern help!

CC

My little one is four days old, she was a pretty long nursery the first few Fahd and we struggled to find comfortable latches but we did it! She would be on 10-30 mins while i just had colostrum. Now that my milk has come in (about 18 hrs ago) she’s much sleepier and will only nurse for 5-7 mins each time before dozing off again. I’ve tried lots of little ways to stimulate her to stay awake. I’ll my supply suffer?? She’s hard to wake during the second half of the night too...will that finish supply as well? Is she getting enough milk? This whole thing is soooo tricky and intense I can’t help but second guess myself. Here’s pics from the last day or so since my milk came in
