6 month old ready for only 2 naps???

I feel like my 6month old could be ready to transition from 3 naps to 2 naps but everything you read online says that 6 months is pretty early for only 2 naps.

The schedule i am try to keep him on is 2.25/2.5/2.5/2.75 and I cap is total daytime naps at 3-3.5hrs. But lately his schedule has been looking more like 2.25/ 2.75-3/ 3-4/ 2.5-3. He has been fighting the third nap of the day so hard for the past week and these long wake windows have been putting his bedtime so late!

For context he contact naps for all of his naps and the first 2 naps of the day he falls asleep pretty quickly but the third nap is a nightmare. He is sleep trained for nighttime sleep and does pretty well overnight, generally only wakes up once to feed.

Could he be ready to drop the third nap? Should I adjust his wake windows? If I do try to do 2 naps what schedule should I try? Any advice or insight would be great!
