When I was younger, I did not enjoy cheesecake. I have distinct memories of envisioning a cake made out of cheddar cheese, especially because I saw the New York style cheesecakes that were sort of yellowish and golden on top. (The thought of cake made out of cheese, for dessert, did not appeal.) I also did not like cream cheese. Even the flavored varieties tasted distinctly sour to me. (I can probably count on one hand the things that I didn't like as a child. Cream cheese was one of them.)
I probably wouldn't offer cheesecake as the only dessert for a party that specifically caters to children, unless it's very very sweet and on the soft side (bordering on pudding/mousse). Kids might enjoy putting on their own toppings (chocolate, fresh fruit, caramel sauce, fruit sauce).
I remember my first positive experiences with cheesecake rather clearly: one was miniature individual cheesecakes served in cupcake liners. There was a graham cracker crust on the bottom, the "cheesecake" was quite wet and sweet, and there was half a strawberry on top. The second one was, believe it or not, frosted. In retrospect, it was probably just highly sweetened sour cream, but covered with fresh fruit, it was delightful.
So, basically, I think it's risky.
