7 month old sleep advice please. Please comment

My son has always been the best sleeper. He slept through the night since day 1. Whenever people asked “how does he sleep for you” I always say I get more sleep now more than I did being pregnant lol. The last month he started waking up 2 times a night to eat but went right back to sleep. He will go to sleep at 8-8:30 pm. Wake up around 4 than again around 7. He will than sleep until 9-9:30am. Hes such a happy baby and he made the whole first time mom thing pretty easy on me.

Anyways my aunt (not too close with her nor like her) we were at my moms house and we were all talking and I mentioned that my son will sleep from 8-8:30pm to 9-9:30pm and my aunt said that was ridiculous and selfish that I’m letting him sleep too long instead of letting him play in the morning and he needs to wake up earlier because that’s too long. Is this true???

I’ll add he doesn’t take good naps. He takes a few naps throughout the day not even an hour long
