EAT/SLEEP QUESTION about 11 week old?

My 11 week old eats 4 oz every 4 hours and goes to bed around 9:30 pm. She sleeps until 2 or 3 and eats. She falls back asleep until 5 and wakes every hour after until 7:30 or so. She eats when she wakes that last time. She usually takes a 2 1/2 hour nap once and little naps after that. She has to be swaddled to sleep for a long period and has to be in swing or held during the day to stay asleep. She sleeps just fine in her bassinet at night though. I guess my question is if this is a normal pattern. I forgot to mention that she has to be almost completely asleep before she goes down at night and completely asleep before you can put her down during the day.
