We MUST rest

I am STILL not giving up on the nap-time for Jonathan. I feel he STILL needs AT LEAST 20-45 minutes to close his eyes and rest DAILY. BUT, ALAS, it is ALWAYS a fight I do NOT want to have... And so, I give him a few books put him in bed and tell him he MUST lie down, read and TRY to rest.
He seems to ONLY fall asleep on Karate days...
Can you guess what today was?

He happened to be napping inside one of our pillow-cases. Not quite sure how that happened.
