Toddler bed ready?

Hey mamas! When do you think is the right age to switch to a toddler bed? My LO is 14 months old and falls asleep on her own in the crib and doesn’t move all night. We have another baby due in March and thinking of moving the crib into new babies room and getting her a toddler bed. Any tips? Advice? I literally have no idea what I’m doing 🤣
