I did try once or twice to let her settle & to be honest and it was bloody awful. DD was hysterical & I ended up crying.
Just a hold of her hand used to make her smile.
She always wanted to be near me/on my shoulder/in a sling.
Someone said I was the centre of her universe & I suppose thats so true.
So here we are years later & still cosleeping.
She does go in her room occasionaly.
I never thought time would go so quick, I miss her when Im at work, I miss her when shes at Nursery. Even though her non stop chatter drives me insane 
I will miss her when shes a big girl, off to Uni, I will worry every second.
All this cosleeping business has Im sure contributed to the fact that she is the most confident & independant little girl.
I just went with it & its fine.
