When homeschooling and doing daycare you have to look at the schooling as being the most important and then adding in only the daycare children that fit with the program in the sense of not having all babies. At the same time there are several blogs on line of parents that homeschool and how they adapted as each new sibling was born. If you are doing it and put that in your info you may attract like minded parents and end up with peers to school together.
The biggest thing is to remember that homeschool doesn't have to have set hours. There is no reason why you can't set up some things in the morning that child needs to learn too but that are mixed into play like playing with letters but is actually spelling out his spelling words or phonics word families. Have him read alone for awhile, watch a discovery network video and draw something from it, etc. Then during naptime you work more one on one with him and also in the evening as well. Things like science experiments can be done with you and your child but the other daycare kids watching and/or helping too.
