What age did you switch from bassinet to crib?

My little girl is getting too big for her bassinet but I'm so not ready to move her out of our room to her nursery yet! She is about 7 weeks old. We will squeeze her in there as long as possible :) Our crib won't fit in our room unfortunately.. how old was your little one when you moved them? 
Also, These pics are taken while we were playing and she's supervised. She sleeps with a sleep sack or swaddled only!
