I have a home daycare and I disagree with some of the other mommas replies. First, your daughter has been attending for several months now, you obviously aren't happy with the level of care and you have every right to switch to a different daycare. However, I think you owe it to the daycare to sit down and at least attempt to have a genuine conversation with the director. Outline your concerns and why you are switching. Unless they are aware of your feelings, they likely won't change anything. Perhaps they will make at least a few small changes that would benefit all the children in their care. If you feel it is necessary, wait to have the conversation on your last week there.
You have likely signed an agreement that would include 2 weeks notice or payment for 2 weeks. I would be very surprised if this wasn't included in your agreement. The daycare is likely counting on a set number of children to meet expenses.
What were you expecting in terms of care for an infant? There is only so much that can be done when caring for a number of infants at one time. Cuddling, diaper changes, feeding and some basic play time is about all that one caregiver has time for, feeding infants is time consuming, and there were likely 3 babies per caregiver. I understand you are expecting more as your baby is growing and developing. It seemed that too many mommas were overly critical of the daycare, if you feel I am wrong, why would you have left your daughter in that daycare for more than a year.
