My son is 2.5 and still in a crib (he has ASD). He's on the smaller side so it's ok for now. I'm scared at the thought of having him in a bed because the kid gets into everything, I mean EVERYTHING and I'm terrified he would strangle himself with the blinds or mess with an outlet (even though I have covers on them), etc. I never had to worry about anything when my older (NT) son was his age, he never touched anything (or at least it happened rarely).
He also rocks and bangs in his crib to self soothe and will do it for hours at a time, every night. If I took him out of the crib I'm worried he would do it against the wall, which is much harder than his crib. And lastly, I worry he would wander the house while we all slept.
How long can I keep him in a crib (he isn't climbing out and hasn't tried yet, shockingly)? How long did you keep your child in a crib (your child with ASD)?
