Last nap & bedtime

When does everyone’s babies wake up from their last nap? And what time do they then go to bed?

My son, who loves to sleep, has decided he doesn’t want to take his last nap. This means he’s up from around 2 until after his 7pm bottle. The last 30 minutes or so he’s sometimes (understandably) miserable. He maxes out at 1.5-2 hours between naps for the rest. Anyone else’s baby decide the last nap of the day isn’t needed? I’ve tried to adjust his others accordingly so he’s asleep until 3-3:30 but he wasn’t having it.
