Your daycare children ages?   
I think it would be great if you had one room a sleep area, colors, decor very cosy.   
Another room you could use as a play room, toys, books around a cozy reading area. You could decorate in bright child friendly colors and give it a really fun feeling. I do like the crayon idea, lots of color can be added with that scheme.    
The last room maybe could be a place for your table for eating and doing crafts on. Maybe you could have a spot for each child's belongings. You could decorate it like a classroom with the alphabet along the top, day of the weeks charts.... You can buy them at staples.     |
