The issue has been that once I announce that naptime is either approaching or imminent, he stages a protest using one or more of the following arguments:
"I'm NOT tired!"
"It's NOT naptime!"
"I don't WANT to take a nap!"
"Naptime is bah-humbug!"
Coincidentally, we have also been working on not talking back.
So, today, with half an hour to go until naptime, he came looking for me.
Isaak: "Mommy, is it almost naptime?"
He just likes to keep me on my toes.
