When is everyone planning on switching their baby to their crib to sleep at night?

My daughter is 3 months old today & she has slept in the bed with me since she was born. She has napped in her crib a few times.

When do you all plan to transition?

Im also stuck on how she’s going to do with sleeping alone when she’s not used to that.

Any suggestions or advice would be helpful. I’m sure it’s going to take some time to accomplish!
