Yep, its time! Dont want her falling out an getting a broken bone. I was very anxious about transitioning my son, but it went great. We got him a (hand me down) race car toddler bed, and when we broght it home we washed it with a bucket & sponge in our front yard (just like a real car), and he helped. then we took it too his room and set it up. We immediately took the crib down and told him this was his awesome new big boy bed. He loved it. I was very pleasantly surprised that he STILL does not try to climb out of bed. I guess he was about 26 months or so when we transitioned, and now he just turned 3. Once he is in bed, he does stay there until we come get him. I know that wont last forever, but it has lasted a solid 6 months now! We were anxious too b/c he was not a good sleeper as a baby and it seemed like it took forever to get to that awesome 8 to 8 sleeping schedule and we did not want to mess with it. But he started to try to climb out, and then one day a little girl in his class at day care came in with cast on her wrist from falling out of her crib. Her mom told me she had already ordered the toddler bed and everything but it was just a few days too late! She was fine, but we decided it best to switch him right away. Dont change your routine, just change the bed. And dont get in the habbit of laying with her unless you want to do that forever :)
