C.-
I am a daycare home provider for 16 years. In my experience, many children have called me mommy. It is very normal. The child is recognizing her as a loving, nurturing person that is caring for him on a daily basis. With my young daycare children, i will work with them each day, non chalantly and tell them my name, when they use "mommy". It is very important to me, to talk to my parents, that I am a professional childcare provider and I will never replace their parents. That together, we can be the best we can be, for your children. Please, discuss with your provider your concerns. If you have a very loving, professional provider, she will reassure you and work with you to be the best she can be. No concern is stupid.. All is valid, if it is valid to you. I hope this helps, and good luck.
