I don't have a 4-year old, but a friend of mine does and has been co-sleeping with him since his transition from the crib.

There is a lot of fear in him (monsters in closet, dark, etc), but Mom too is now attached to this (their new normal, wanting her DS safe). The DH has resentment toward to the Mom over this.

I am sure there is lots else going on, but in terms of trying to think how one would transition away from co-sleeping (in his room, in his bed) back to her room at that age, how do you even do that? I only co-slept newborn days and DD is currently still in crib, so it's all mind boggling to me how you would rationalize the transition with a 4-year old.

Any ideas?
