Your baby now is well adjusted with her life and schedule. Any kind of change in that may cause some amount of stress for your baby but she will be able to handle a few hours of separation from you provided she is well fed, is not tired or irritable and occupies with her play. She is now willing to adapt to a new person for some time.
What you need to know
It is best to have a set schedule for the day for your child. When you assign someone else to take care of your baby in your absence, make sure that the person also follows the same schedule. This helps your child adjust better and reduce stress and anxiety.
