No, that doesn't sound dumb at all! I think it's wonderful that you are taking your studies so seriously. It's even better that you want to be such a good parent, even if it is for an... admittedly fake dragon egg. It shows that one day, you are going to make a fine parent.

I really feel like I should look into seeing if I can get the two of you a real dragon egg to hatch together as a more advanced school project. You would not be able to keep the dragon, of course. But it would certainly be educational!
