Middle of night feedings

Okay mommas! I am a first time mom with a 3 week old son. He is breastfed (nursed or by pumped bottle so hubby gets a shift).

In the last 4 days he has slept 5-7 hours though the night which is an absolute blessing in my opinion. Online I'm seeing contradicting info. Some says that newborns must be fed every 2-3 hours and the others say baby will let you know when they are hungry.

This morning i actually woke him up after 6 hours because 1. I was engorged and 2. I felt like he needed to eat. Should I be waking him up in the middle of the night to eat or just start enjoying this new sleep pattern while it lasts?

Any advise would be great!
