Your baby is transitioning to being part of the world. I would minimize play and concentrate on getting breastfeeding well established and resting. Play comes later and for my kids never, ever just before sleep. Boobs are the best way to put a child to sleep. No crying, no fuss. Not many babies can self settle, and I'm not sure why we try and achieve it when they are so tiny. As others have said, there is plenty of time to worry about all that.
