I have a 2 year old that has a similar pattern. I notice that he usually first awakes when he pees in his sleep. I would change her diaper. Also, when he naps well, he sleeps well. When he is on a consistent nap schedule, he tends to sleep better, though not always. Try moving her bedtime up half an hour, make sure her naps are consistent and restful, and when she does wake up, change her diaper & console her just as you've been doing. I know this leads to awful, sleep-deprived mommy and daddy, but sometimes "patterns" are just that... teething, growth spurt, light sleeping, etc. My first born (now 10 yrs old) never slept well either. Around the age of 6, he finally settled into a wonderful sleep pattern. He has apnea, also, which could've been part of the problems he had as a baby, so you may want to do a sleep study if you feel it's really becoming a serious issue. Otherwise, just try your best and know that she won't always be waking like this. (I don't know if that advice is helpful or not...) :)
