DS4 (last night at bedtime - when all the questions seem to appear) "where did the first person on earth come from?" I could deal with that one.

Today I had "who dresses up as the Easter Bunny?" DH and I just sat there grinning, we didn't know what to say. I don't like lying to them because they trust us so much and it is such a fine line! I still remember when my older DS (who was then 5) asked me if we pretended to be the tooth fairy, but then he said "that would be ridiculous because why would you pay me money for my old teeth - what would you do with them?"

Now the big question that DH and I try to avoid answering - "how does the sperm get to the egg?" It is hard to know how much detail they can handle at such a young age.

Yes, questions are relentless in our house!
