I Want to Have Christmas

I was woken up this morning with the sole request "I want to have Christmas Mommy!" What do you say to that? Especially in the middle of April? I had to explain to him that it only happens once a year and in the winter and since it was no longer cold, we had to wait. He nodded his head but I heard him muttering "Jingle Bells" under his breath while walking away from me.
