Lmao, so did I. I would even try to wake her up, but she just wanted to sleep. Right now your babies tummy is tiny, so she doesn't need much food. But eventually she will be waking up more and more. My daughter sleeps for about 2-3 hours, wakes up and eats 3-4 oz of formula, then goes back to sleep. Except during the night, she likes to stay awake for about an hour each time she gets up. Enjoy your sleep while you can, lol.
She's a newborn. That's what she will do for about the first 2 weeks. By the third week she will be awake much more. My daughter will be a month old this Saturday and that's how she was.
