Any almost 10 mth olds on 1 nap already?

DS schedule was clockwork. up for day at 7am, nap from 10-12, 2cd nap from 3-4 bed at 7pm. He puts himself to sleep, no fuss no crying, sleeps through the night. I have worked my A&$ off to make it this way. I began waking him at 11:30 because he seemed to not be tired for his 2cd nap if he slept until 12. So the last 3 nights he fusses/cries for an hour after being put to bed before sleeping. Today for his 10am nap, he talked to himself for 25 min before sleeping. He still sleeps through the night THANKFULLY because I CANNOT function on no sleep.

Do you think he may be ready for 1 nap mid day? He was "early" to drop the 3rd nap, and has been on the schedule since 5 months old. Any suggestions/ experiences welcome!!!! TIA!
