My DS1 is 23 months and sleeps and naps happily in his crib. He is physically able to climb out, but never has (he's a pretty laid-back kiddo). I'm due with our second child in a month and am wondering about when/how to transition DS1 to a big kid bed. Though he's a pretty flexible kid, I don't want to overwhelm him with change when the new baby arrives. I'm also really reluctant to change his sleep situation because I love his 3 hour naps and don't want them to go away right now! We'll just be taking one side off the crib since the new one will be in a co-sleeper so we don't have a need to get DS1 into a different bed. I'm just worried that I'm going to hear a loud "thunk!" one night and he'll hurt himself climbing out. Should I try to transition him to the 3-sided crib now (with 4 weeks to go before #2 arrives) or just wait a few months after the new baby and hope he doesn't climb out before then?
What ages have you moved your tot out of a crib and how did you help him/her make the transition?
