Having trouble getting toodler to Sleep

Hi imperfect mum's my almost 2 year old is a really bad sleeper if she sleeps by herself in her own room she will constantly wake up every few hours, I usually go and sit with her until she goes back to sleep but she can wake up like 5 or 6 times a night, I have noticed she is a light sleeper, I have a night light on her room I leave on and a fan, I'm running out of ideas, I am also in my third trimester so I'm tired all the time haha, in the end if she doesn't go back to sleep I put her in my bed so I can get a bit of sleep, I'm so lost with what to do, she needs to sleep in her own bed but have no idea how to make her. Help please
