Sleeping issues

My almost 4 year old will not fall asleep on her own and actually wake up in the middle of the night to come find me to cuddle her back to sleep. She has five nightlights and even a fish in her room to keep her company. I’m 9 months pregnant and I’m at a loss. I need my sleep and so does she. Her little sister sleeps like a champ alone in her crib in another room no nightlight but this one is completely opposite. Anyone have any tips …. :(
