toddler still wake up in the middle of the night

I hope we’re welcome here. I’m 15% Asian according to my DNA results. My wife is Mexican. I hate stereotyping, but Asian children are far better behaved and more intelligent than lazy Americans (we’re both math teachers). Ours just turned six months. He may wake up once or twice, cry for a couple of minutes, but goes back to sleep when he realizes we aren’t coming for him. Typically we’d have no idea because we turn the sound off of our monitor. Only reason I know he wakes up is because I pulled a couple of all nighters working from home.
