Can she see you from her crate when it's bed time? Perhaps try covering her crate with a breathable blanket but something that will cover the light and keep it dark for her.
When Kian was that age he would whine as well and we just ignored him. He would soon realize we were not going to go see him. If it got out of hand then it meant he had to go potty. Some times, not all the time we would give him a few "ssh, go to sleep Kian" and he would settle down after a few minutes.
Also make sure he is not having accidents in his crate, he could be fussing because his crate is wet. Just a thought.
Good luck, it will get better :
....I promise ;D
