Toddler struggling with transitioning to her own bed

So we have started transitioning our toddler to her own bed. We had lots of issues last year with me sick with cancer and in and out of hospital. She cries and wakes up easily. She has cows milk at bed time with story time and then her sleep music goes on. This routine has worked well after bath time. She also has an anxiety breathing bear as well as her bunny rabbit. Just not sure what else i can do apart from reassuring her she is okay. Keep in mind she was in our bed for 3 months when she was very sick for 3 months. Any ideas would be great.
