When did you transfer to a crib?

Hey ladies, my babe sleeps partially in his bassinet and partially with us right now. He’s 4 months old. Question is when did you transfer your LO to the crib? It’s hard to me to think about him being in a different room so id like to keep him in our room at least for a couple more months. He’s growing out of his bassinet so I’m just curious what y’all did with your little ones.
