Is your day care licensed with the state? If they are they have certain regulations they are required to follow. There should be a web site listing those regulations on the internet. You can also contact the licensing bureau to see if the Day Care is in good standing with the state.
A licensed day care is only allowed a certain number of children. Your child should have a bed assigned to him. If they can't show you one, you have a legitimate concern.
Are you allowed to "drop by" to see how your child is doing during the day? If not you need to change day care's as soon as possible.
The bottom line is that if you are not comfortable with your child's care you will both be unhappy and you will not be able to relax at work. If your insticts are telling you something is wrong, listen to them. Your child and your peace of mind are too important.
