3.5 mo sleep

I keep seeing a lot of people share that their babies go to sleep between 6-8pm, but my 3.5mo baby wakes up at 7am and sleeps around 10pm everyday. He gets around 5 hrs day time nap and sleeps through the night (at most 1 very short feed) Is this normal? And for experienced mummies, did the bedtime move up at a certain age? I tried to shift his routine to earlier before but he couldn't fall asleep. also didn't hit his milk intake for the day
