Both of my children have Autism, and neither liked being in the crib. I moved my older one of the crib just before age 2, as my younger son would be needing it, and both of them slept MUCH better once I did (this was before I knew they had Autism (diagnosed at 2 1/2 and 3 years respectively).
Since they both tossed and turned in their sleep, when we moved them out of the crib, we put them in queen sized beds (with head and foot boards, against a wall, and with a mesh side rail to keep them from falling off)--they each have their own bedrooms. When they were about 4 years old, I removed the side rail from their beds.
