Third nap or earlier bedtime?

Michaela

Hi ladies, my boy is now in transition from 3 naps to 2. Last week he had just 2 naps and bedtime usually between 6.30-7.00pm.

Today he woke up 7.00, his first nap was 9.30-9.55. His second nap was 12.55-14.25.

He can't stay awake before bedtime longer than 3,5hours, otherwise he is fighting sleep and keeps waking up. I am not sure now If i should give him some cat nap as a third nap or is it just ok to put him in bed early today at 6pm???😴🤔
