Toddler bed transition

Chelsea • Mama of 2 👶 and 4 😇 TTC #3

Need advice!

My son will be 3 Feb 22. Today I transitioned his crib into the toddler bed. He is super excited but I really don't know how this boy is going to stay in bed.

He is the type that never sits still, but he was showing signs that he was ready to be in a bed. He isn't potty trained yet.

My questions:

How do you keep your toddler in their bed?

Do you keep their door open or closed?

Any other tips?

Thanks!
