Last week Aidan climbed out of his crib. It was just once and hasn't happened again. I'm tempted to take the front off of his crib and make it the toddler bed, but then I'm worried he'll fall out or not sleep as well. (We put him to bed asleep, even at naptime...I know, shame on us!)
When did you make the switch? Did your child's sleep habits change?
Re: switch to toddler bed
We switched our daughter just last month. She wasn't a climber though. She just needed to move out so we could get the nursery ready for her baby sister.
Our first night was the hardest but she was in a new bed in a new room. After the first night, she went back to her normal sleeping routine. She will stay in her bed until someone comes to get her in the morning.
