When do you transfer baby to crib?

My little girl has been in a crib since 2month old as she outgrew her Moses basket she still sleeps in our room she’s now 5months

Our little man moved over just before 4months old as he'd also outgrown his next to me. He's in his own room in his cot (though the past couple of nights he's been in ours because of the sleep regression ☺️)

My little girl slept in the next to me and outgrew it by 6 months so we then moved her into a crib
