Early wakes during 2-1 nap transition

We recently transitioned my 16 month old to 1 nap. We were running out of time in the day for 2 naps despite capping them both at an hour, and he seems easily able to stay awake for the necessary wake windows for 1 nap, so we went for it. It’s been about 5 or 6 days so far.

Since making the change, we’ve been getting early wakes (between 5-6am), and I’m wondering if we need to make any schedule changes to account for the early wakes or just keep nap time the same and push through while he adjusts?

Our schedule is:

7am - Wake (although lately this has been earlier)

11:30am - Nap

1:30pm - Wake

7:00pm - Bed

ETA: he’s been sleep trained since 8 months and falls asleep completely independently for naps and bedtime, typically sleeps through the night unless a tooth is breaking through
