So, my little DS has now transitioned to A time of 3.5-4h! His am nap is between 1.5-2h with this A time. However, he is now refusing his afternoon nap. Won't take it with motrin, or teethers or any APOP. He does fine and seems very happy until his bedtime at 7:30pm and still sleeps through the night, so far. Any ideas? This is way too early for one nap, right?
