For us, moaning means some sort of discomfort. Any chance the ears still hurt some, or teething? Have you tried any pain relief.
Not sure what to do about the rolling over - persevere and she will get used to it, I am not sure of any way to stop them rolling, but my DD couldnt sleep on her back so when she started rolling I had to roll her over too, but then she learned to roll the other way.
