Newborn sleeping at night

My 6 week old baby boy will wake every 2.5-3 hours during the day to eat, then play (or vice versa), and back to sleep. Does anyone else's little one sleep 4-5 hours overnight? This is my second but my first was up every hour or less to feed due to hypoglycemia so this sleeping longer stretches overnight is new to me. I have talked to his pediatrician and she said he his fine to sleep but just dont let him go past 6 hours overnight between feedings. I guess I'm just curious how many others are sleeping that long at night.
