It might not be illegal but it definitely seems inappropriate. You really think it is appropriate for a religious day care to hand out flyers in a public school? I wonder how the school and other parents would feel if it were an islamic day care or a pagan one? I have a feeling it wouldn't go over well.
Also, I bet an islamic one wouldn't be approved by the school board.
I really want to know if this place got special treatment. If the daycare my friend manages can't get her daycare advertised at the school without going through the school board... I have a feeling that this one didn't go to the school board. I intend to find out.
what you're advocating is special treatment, like a religious day care should be excluded when others are allowed. THAT is inappropriate.
