I put my son in a 'car bed' at 16 months because we were expecting #2 when he turned 18 months... and in time we would need his cot for the new baby.

My son is a notoriously bad sleeper - so I was very nervous about him getting up during the night and playing.

This has been my experience:
- we put him to bed and he will sometimes have a grizzle but he will usually go to bed/sleep. We close his door when we first put him to bed (and open it before we go to bed).
- if he is really restless - he will get up and cry at his door until we come to him. Then he will usually scurry back to bed and dh or myself will lie down with him until he goes to sleep (thankfully car bed is a full size single mattress).
- He stirs at midnight...but rarely gets out of bed
- he nearly always gets up around 4am... and comes into our bed for a few hours co-sleeping.
- occassionally he sleeps through to 7-8am or wakes up in our bed... then he goes into in 'play room'.

I have been lucky enough to move into a house with a spare room that we put all their toys into... so I have removed toys from Shauns room - leaving teddies & books. Sometimes Shaun gets "busy" and removes all the teddies from the shelves/bookcase. Often he sits up and reads books to himself. But he doesn't have toys around him to keep him from sleeping.

I have put a night light on in his bedroom. It's bright enough that we can see him,and he can see around his room - without being too bright that it distracts his sleep. Shaun has always slept with a light on (whether it be night light or main light on dimmer).

I wouldn't be worried about Krystal not finding your room. I was amazed how well Shaun learnt to get in/out of his bed, and find his way to our room or his play room.
