Is it ok to let 2 month old sleep 11 hours every night ?

Amy
She knocks out at 1am then wakes up at about 5am or 8am to eat, after that she wakes up one more time only to eat and then falls straight back to sleep to wake up at 12pm. Once it's 12pm she's on a schedule where she stays awake for about an 1hr and a half then naps for 2 hours or less. Then at 1am it starts all over again.
Is it normal ? Is her schedule ok?
