Sleeping soundly

My little boy at 6 weeks + really moves a lot! Almost 90 deg while finding a comfortable position at night to sleep. He squirms and grunts. Like tonight, he wakes up at 3.45am to bf and then when I put him down at 4.15, while I sit down to pump and empty the breasts, he was grunting away. And when I finally finished my pump 30min later, here is his final position.
