I work in childcare if you want to connect . Have you found her a spot ? Most places allow you to transition the child , by starting with half days then doing full days . As for diaper changes, there are apps and they are required to log it in. As for how she is treated , I cannot say as I don’t work there. But it’s normal to feel nervous my dear.
Daycare is a difficult step for all parents. I guarantee your baby will feel more attached to you. And if they are attached to the daycare worker, take it as a great thing that your baby is forming new relationships. ❤️ Follow your gut when choosing the right daycare for your family and never hesitate to speak up and ask questions. The transition is a hard one, not gonna lie... But it's worth it when you feel like your child is happy and you have a good fit. Good luck!
