My 10 week old had been falling asleep around 7pm for an hour or so and then going back down around 10. Recently (the last five nights) he's been going to sleep at 7 and not waking up for 4-6 hours. Should I wake him around 10 to feed and change his diaper and put him back down? My hope is by doing this we could then get only one wake-up instead of two (at 11:30/12 and then 4). He's a big baby (99th %) and can definitely do long stretches.

Waking him goes against my rule of never wake a sleeping baby. Any experience with this??
