Unfortunately, I think you need to wait it out. :( My son was exactly the same way - not sleeping at all - until I started giving him formula & rice cereal at 5months then he started to sleep a little better because it coated his stomach. Then, he was teething from 3months to 8months and those months were difficult because he was always up. However, he did not get any teeth from 8months to 12months and it was awesome because he slept really well. Then, he started teething again around a year until now that he is 16-months and he has slept awesome - I think we just waited it out. Unfortunately, I think the Pediatricians give the worst advice when it comes to sleeping. It shouldn't be based on weight, or giving them water instead of milk, or letting them cry it out. All of those are just awful, I generally back up what a pediatrican says 100%, however the sleeping issue is exempt. I think it based on the individual child and even though it is awful on us parents (with no sleep that is) we need to wait until the kids are ready and they will let you know. My son sleeps uninterrupted at least 12 hours a night and during the day takes 1 nap any from 3 to 4 hours. We do keep a set routine which I think contributed to him knowing he needed to sleep. We have him brush his teeth, take a bath, rub lotion all over him, put him in his crib with a bottle (and let him stand, sit or lay down - whatever he chooses) read him a story (and point out all the common items, e.g. chair, bed, bear - if you coulnd't tell it is usually goldilocks we read him). We turn out the lights and play Bach or Bethoveen really low (all night on repeat) w/a cool mist humidifier and I lay him down, let him continue drinking the rest of his bottle and sing to him, count backwards from 20 letting him know that he is going to hand me the bottle and go to sleep. Then, he hands me the bottle and I blow him kissing and tell him what a wonderful baby he is. He lays there smiles at me and goes to sleep, I shut the door. He never cries. He never goes to bed thinking he is being punished, it is just a beautiful thing to go to sleep. Hope this helps, just don't make his bed this horrible place to go, make him feel comfortable in it. It will happen just give it time - when he takes naps during the day try resting too - if you can get your daughter to go down to.
