Hey same problem here. Here's what we did.. We changed over her bed to a toddler bed but she hated it so we had to change it back to a baby bed. We did this for months and she just wanted didn't want a big bed. We finally went and bought all Dora bedding and changed it over and she loved it. I think it is just how the child feels. When we started she didn't stay in bed, she would come and climb in bed with us so we put the gate back up. Then we had to go and "sleep" on the floor till she was asleep then we could go to bed. Now she has this thing that she has to sleep with the light on. She'll stay in her bed and talk to her babies and we just let her go to sleep on her own.. I thought my child was worried b/c she didn't want to get out of her baby bed. She never even tried to get out. Well good luck and hope this helped.
