What can I do 😫 parents!!

My 2.5 yo recently has started fighting bedtime. We are having a baby which she knows about and we recently moved her room. She was doing excellent down there. She’s always eager to climb in bed, drink her milk and read a book. We do all that and when we leave all hell breaks loose and she gets out of bed multiple times. Last night I took her blanket,lovey and music she is so attached to see if that helped any and she’d listen. She cried and cried and finally fell asleep. Than like always woke up at 2:30 crying, wanting milk than would not go back to sleep again. She ended up sleeping on the floor in our room. What can I do?? 😫😫 is this a phase? I’m absolutely exhausted. She always tells us she “wants us”. Usually to lay with her or hold her hand. Any suggestions would be great!
