When to transition to a toddler bed?

Ki

I know it’s pretty early, but when do you know? Is it just a gut feeling? My current crib turns into a toddler bed by removing the front gate and making it shorter.

I read it’s between 1 1/2 and 3 1/2 years old. Which seems like a wide range. For those of you with older kids, when did you know it was time to switch?

My current plan is when I know he can safely get out of the bed easily. But he still struggles with getting off the couch without going face first. 🤦‍♀️
