When to switch to toddler bed?

Sh

When did y’all switch your child to a toddler bed or anything other than a crib? My little guy is really tall and he is only 10 months and he is already kicking the sides and having a hard time getting comfy. So when should I look into switching him to a toddler bed? 1 year? 18 months? What did y’all do? Thanks you!
