Thanks guys!!!
I have talked to her and she actually seems excited about a bed. She kept saying "NO LINES, NO LINES" which I guess is the cot bars....felt so bad as she obviously does have thoughts about her cot!! Anyway, I said "No more lines" and she was like "YEY"!! I told her we are going to pick out some sheets and a pillow so she seems happy.
Still not sure how the actual transition will go, but good to hear others have done successfully with similar type children!!
MBear I'll be prepared for some late nights when I move them in together!!!
thanks again guys xo
