Baby Sleep: Did anyone have their newborn sleep in their own room/nursery?

Karelta

Hi, my baby is 3 weeks old and my husband has suggested that we let her sleep in her own room in her crib every now and then at night so she can get used to it so when it’s time to transition her she is ok. She also does like napping in her crib sometimes. I want to know if anyone else here has let their newborn sleep in their own room/nursery? How did it go? Any regrets?
