My direct advice is to find ways for yourself to continue to run and grow your business while you establish a different, satisfying child care arrangement for your boy. You know you will be a better mommy to him if you are being fulfilled yourself; if you keep up this present arrangement it seems like you are not going to be the mommy you want to be or the creative gift basket person you want to be. You and your son both suffer in this present arrangement. Whether it's a part- or full-time good preschool arrangement, or a cooperative baby-sitting arrangement, or your renting some space outside the home while someone comes in and takes care of him for certain periods of the day, you need to make finding an alternative arrangement a top priority. Don't feel guilty about not being there for your son 24 hours a day; I bet he will get all the love and great mothering from you he needs in this new arrangement. You do have choices here (unless economically you can't consider any other arrangement) that will only improve life for you and your boy; the transition may be bumpy but I'm convinced you'll both ride it out and have a much smoother ride ahead.
