Yes, it is possible

Yes, yes.  It is possible for a nine-month old to go an entire day from 6:30am to 9pm with NO nap.  Not a hint of a nap.  Luckily, he was happy for all but the last 30 minutes of it.  But then again, he usually is happy.

But I was secretly hoping to take a nap with him for a couple of hours.  Rats.
