Does anyone's babies sleep all night?

My daughter has been a blessing to us. We feed her around 9:45 10:00 and she doesn't get up till about 7:30 8 in the morning. Once in a blue moon shell get up at 5:30. But even at that it's good. I wonder if this is healthy. She's been doing this since she was about 2 weeks old. She's now 7 weeks and 6 days
