LOL! At 4 DS was painting pictures of sperm. We have one
of his paintings framed and on the living room wall. There are
three big blue sperm with black tails-it's a great picture!
His preschool teachers thought his sperm pictures were
hilarious.

If your child asks again, tell him a sperm and an
egg come together to begin making a baby. Ask him if he has
any more questions....the next question our son asked was,
"What does a sperm look like?" We went online and got him
some pictures of real sperm. Hence the paintings. Again, we
asked...any more questions? He said no. At that age, we tried
to answer the basic questions and complicate no further.
