How long should baby sleep?

Teo is 2 days shy of 2 months old. He slept 4 hours and 40 minutes in one go last night. He’s been sleeping 3-4 hour intervals at night. I just let him sleep. When he wakes, he’ll take his normal 2oz feedings, sometimes 3oz.

I figure that since he’s suppose to eventually sleep all night, and be awake during the day, it would be fine. Currently, we put him to bed around midnight and we wake him up around 1AM. I understand that it’s a very late bedtime, but that is how our day generally goes. Is he sleeping to much in one go? Should I wake him up to feed him?

As bonus, he’s a picture of him. He was sucking on his pacifier so hard that it left indentions.
