You need to set the legal matters first. Check the licensing policy and the state regulations. Licensing will give your business insurance and also credibility. Your day care will become listed and this will attract more attention and people would come to know of you.
Plan each day as the parents like to be informed about how their children will be spending their time. List down the activities that you will have each day: circle time, play time, crafts time etc. This way a proper routine will form and even the children would be ready on how to spend the day. You could also include a field trip once a week if it’s manageable. Allocate an area to conduct each activity. The living room could be for naps or watching cartoons and family room is for playing. Use the dining table for art related activities. Also set a space in the lawn for some outdoor games. Another option is to take them for a walk.
Design a poster and print some pamphlets for advertising purpose. Add your complete home address and contact information on it. The fliers can be delivered to the homes in the neighborhood. Also before you formally start, have an information day where you could tell about your rules and rates. Have some refreshments; give the parents a tour and a plan of how the day will be conducted.
Have separate interviews with each parent who admits their child. Explain them the details in person, vacation policies and ask if the child has any special needs or allergies.
