When my daughter turned 2, we changed her crib into a toddler bed ( it converted ) and she was fine with that. I put a chair ( the back of it ) by the head of the bed to make sure if she rolled, she wouldn't fall. The problem came when she turned 3 and we switched her from toddler bed to a regular daybed. She had a fit when we took down the crib/ toddler bed. She wanted me to put her toddler bed back up. It didn't help that the day the bed was put up she decided to stand up and jump on the bed
and fell and hit her head giving herself a nice little bump. I quickly told her that jumping on the bed was a major no-no
. It took about a week before she was over not having the toddler bed. I would have left the toddler bed up longer if she had a bigger room.
