My 7 month old woke at 7:22am. He took two naps today totaling two hours. The last one ended at 2:40 PM. It is now 5:50 PM and he has refused a third nap/cat nap before bedtime. His last week window is normally 3.5 hours. It’s now 6 PM so should I do an early bedtime or a late cat nap in late bedtime? His bedtime is usually between seven and 730. He usually has about 11 hours of awake time during the day.
