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

My sister was surprised when on the first day, she asked her toddler if she wanted mama to stay with her and my niece said a flat out no! She was sad about it at first, but seeing how independent her daughter had become made her proud and she saw that she could be more independent too! Without having to worry about her daughter, she had energy to do new things like sign up for a yoga class. She made sure to still bond with her daughter when she came home by letting her tell stories about school and her new friends.
