Re: How long should my baby be sleeping?
My son is almost 14 months old and he only stays up about 3-4 hours during the day and takes a nap. He takes two naps and is sleeping about 10-11 hours at night. So since you're daughter is only 10 weeks old....I would think that staying up 2.5 hours is probably normal, although I don't remember with my son at that age. I'm thinking he did the same thing as well.
