Sleep troubles

I need advice my daughter is 2 yrs old sleeps in her room in her bed BUT….. I have to lay down with her to fall asleep and she is waking up like 2 am or 3 and comes to my room. I have to take her back to bed and lay down with her until she fall asleep again. But I’m 38 weeks pregnant I’m tired and don’t always take her to bed. I’d like to start with her falling asleep by herself first and then what can I do for the middle of the night wakes? Help. Advice! Thank you!
