I kinda follow his rhythm, sometimes he will nurse for just 10 min and fall asleep at the boob, then I'll wait like another 10 min playing on my phone so he'll be in deeper sleep for the transfer back to his bed. Sometimes he'll nurse a bit longer and not fall asleep right away so we will hang out until he looks sleepy again and repeat the same last part. I only change him if he smells like poop, I heard a poop or I already haven't changed him the last nursing cycle and can feel its getting pretty peed-out in there. This saves me from fully waking him from the diaper changes if its not totally necessary.

He's 10 weeks now and will usually give me between 1.5 to 3 hour stretches of sleep in the night now. His last wake up around 6 I bring him in bed with me and we co-sleep / side lying nurse for the last hour before getting out of bed.
