My first question is if you are staying home to be with your baby, why would you want to spend your time doing something that takes you away from them. Yes we normally do the bulk of our activities while babies are sleeping so that when they are awake the big kids have freeplay and I can spend time with the baby. A playyard for your child will become your best friends if you stay with the older kids because it will keep the baby from getting stepped on or into anything she can't have.

I would be more inclined to open as a home daycare and do that for a year taking in children closer to your own child's age and then move them together into the preschool - be sure to lay that all out for the parents at the interview so they know that as their child ages they will have access to the more advanced programming.
