How do you deal with separation anxiety when it comes to childcare for your toddlers?

What has worked best for me has been to approach is gradually and with patience. We spent a lot of time with caregiver, my child and me which helped my child trust the caregiver as mummy trusted the caregiver. We also exposed my child to several new people - family and friends and encouraged him to spend time with them so he got comfortable with new people not just his parents and Nanny.
