<human>: So something concerning me. My wife and I have terrible schedules. We both work at restaurants and both get home late. Recently my 16 month old son has started finally going to bed at 1 or 2 in the morning
The thing is, he gets plenty of sleep. He will sleep for 10 plus hours if he needs to and takes a nice long nap around 4 or 5 in the afternoon. 
We also have a blackout curtain for the room so that he can sleep in darkness for these recent late nights.
What I'm asking is if it's okay for him to go to bed this late as long as he's getting plenty of sleep? 
Just to mention, he's a happy, energetic, well behaved, hilarious little dude. Any input would be greatly appreciated.

Can you condense the text into a few key points?
<bot>: my son goes to bed way late around 1 or 2 am but gets plenty of sleep. He is healthy and happy.  Is it okay?
