Transition to crib

Looking for advice and experience on transitioning my LO from bassinet in our room to crib in nursery. This LO had a growth spurt, and is starting to get too big for her bassinet =/

I have just started putting her in the crib in the evening after a feed. She doesn't nap, but doesn't cry either! I've been leaving her in there for an hour+. She just stretches and grunts, etc. Not sure what else I can do to make the smoothest transition for nighttime? She's 7 weeks old and sleeping from about 10-4:30 in her bassinet currently. Hate to mess that up!
