Her doctor is the person to ask if is okay, only because they know what to check for. Assuming there are no health reasons behind her sleeping pattern, all I can say (with nothing but love and compassion) is get use to it :) My son (18 months) was the same way and still is sometimes. He has never been a good sleeper until recently and it's been so long that now I'm on his schedule and still don't sleep at night. I was never able to nap with him either, I'm not able to fall asleep knowing its only for a short time. Make sure you balance it out though. Crappy sleeping habits usually go hand in hand with crappy eating habits, so take vitamins. When I would luck out and my son would fall asleep it was usually in a position that kept me from moving much so I started keeping a jar of peanut butter and a spoon close by. It's filling, protein filled, and best of all, makes no noise when you eat it!!
