Well, it seems like it might be time to investigate other options. Since your kids are older and potty-trained or near potty trained there might be some more "pre-school" kinds of options out there. Many churches have pre-schools, some more religious than others. I'd start talking to everyone you know - work, neighborhood, community etc, and find out what your other options are for child-care. Some people in your center might also chip-in on a nanny-share kind of program, perhaps in conjuction with morning pre-schools. Keep exploring your options.
