8 week old baby stays up for long stretches?

Sa

My daughter is 8 weeks old. She sleeps from midnight to 8 or 9 (waking up to nurse twice). Then she will usually nap around 11 and again around 2. Her naps are anywhere from 20 minutes to an hour. She also takes a short nap in the evening. After that, she stays up 6-8 hours until bedtime. She just started doing this. She fights sleep so hard. I am not sure if this is just part of the leap she is going through, but it seems like a long time for a baby to stay awake. 😬
