6 week 2 day old, one looooooong nap?

Normal or no? He had a rough night (up 3-5, sleep 5:30-7:00ish, cat naps totaling maybe 30 minutes until 11:15) but has been asleep from 11:15 to now 3:48 (and counting!)

I tested out putting my used breast pads next to him while he’s sleeping so that he’d sleep longer, not sure if that’s working or he’s making up for last night, but will try again. Anyway, is it okay for him to just get one “super nap” instead of a few small ones? Last he ate was 10:40, but he’s been great with diapers and all that.

Is tonight gonna suck? Do I need to wake him?
