Crib transition.
Edit: I successfully navigated the conversation and am changing his bed right now. Many thanks to all of you and sorry that this was not the right group for my question.
My son is 3.5 y/o and 38" tall. He still sleeps in a crib primarily due to my wife's fear that he will wander around at night and unlock the front door which he does know how to do if the baby lock is not on.
He just started using furniture around his crib to crawl out of his crib. For me, this was a clear signal he needed to be transitioned to a bed but my wife instead wanted me to just move the furniture. I thought this made things more dangerous as he would still try to climb out but would have less to use.
Sure enough, during nap today he started crying for us and he was sitting on top of the railing of his crib, trapped without a way down.
Unfortunately, my wife is still not ready to talk about putting him in a toddler bed. I am really upset by this situation and am trying to broach the subject without any doubt that the transition is the move. Ideally, i would use a gate for the door to his room.
Everything I have read says that once they are climbing out then the crib is done, my wife believes it is more about maturity.
Thanks for reading and I would love to hear any thoughts, especially if anyone thinks that I am off base on anything here.
