Could she have reflux? My ds was the same at that age, he woke like that exactly for months from about 10 months old. From 12-16 months we saw drs/mchn nearly a dozen times for help as i strongly suspected reflux, he also vomited a fair few times a week with big choking vomits. They fobbed me off though as he wasnt losing weight (he actually gained an extrodenary amount of weight because of thw constant bf overnight, also a reflux sign). We eventually saw a public paed at 18months, and even though things were fjnally getting better he said i was right and it most definately sounded like reflux. As things were getting better we done a wait and see approach and things continued to improve on their own.
Definitely something to look into perhaps. It really really sucks, i know how hard and how frustrating it is. Gbh xxx
