Help with toddlers sleep

My 3 year old daughter keeps waking up in the middle of the night and or wakes up way to early. We have tried the time to wake clock or whatever it's called and it did nothing. Is there such thing as a sleep aggression at this age?! Lol. She goes to bed at 8pm on weekdays and 9pm on weekends. She does sleep with a night light on/sound machine thing. Is it the night light that is causing her to wake up? Please help a momma out, we are exhausted, any information/opinions is appreciated thank you!😊
