She is hungry. She has grown and is ready for another feeding.
You could try what I used to do with my babies (and grand babies)
Just before bed, give her a bottle of formula with a little rice cereal mixed in. You will need to make the hole in the nipple a little larger for this. I used to insert a toothpick in the hole, then put the nipple in boiling water for just a minute. Take the nipple out of the water, allow to cool, then remove the toothpick. Now, that was in the old days. They are making the nipples out of different materials now, so this may or may not work. You'll just have to try it. If it doesn't work, you haven't lost much.
Or
mix up about a teaspoon (no more than that) of rice cereal with some formula, and feed it to her in a coated spoon, then give her a small formula bottle.
Either way, this will fill her up a little better and hold her off a little longer.
As newborns grow, they need more milk, but their tummies are so tiny, that there is no way they can hold enough milk to keep them satisfied through an entire night.
I had one baby that was sleeping through the night the first night we brought her home from the hospital. While it was heaven for me, the doctor said it was not good for her, and had us wake her up at least once in the night for a feeding.
So ..... your little angel is normal. She's just hungry.
