If you take a look at page that talks about daycare-related grants you will see some information about grants for just the kinds of things that you mention.
It won't cost you anything to find these grant programs if you locate them yourself. Just take some time and do a little research both online and at your library.
The government grant programs are funding programs that have been made possible because of taxpayer money so the information about the government grant programs has to be made accessible to the public. You can go to the government's official website and you can also find the government publications at the library.
However those grant programs that are provided by outside the government like foundations and organizations will require a bit more research on your part.
