Another question

Did your child, at age one, sleep twelve hours at night? Daisy has been sleeping ten if we're lucky--MAYBE eleven once in awhile. (And of course, lately there have been screaming interruptions in the middle of this.) I didn't dare even hope for 12, but I've talked to some folks who are getting 12 and am wondering now. (My sleep book, though, says 9-10 hours at night is the average for a one-year-old, with two or three hours of naps during the day.)
