How did you transition from bed to crib with your toddler?

I never thought this would be so hard! She can climb out of her crib now, but she won’t sleep in a bed. Luckily, right now, she’s afraid of the dark and won’t get out at night, but nap times are chaotic. She either skips it or runs around like crazy until she passes out on the floor.

I’d like to get her transitioned before she thinks to climb out of the crib at night. Anyone have some tips?
