Reading your post made me guilty...haha! My going 22 months old gal also sleeps with us on our bed. I like it and though i realise we will have a problem putting her in her own room, i decided i'll face that issue when she's older.
We are also moving end of this year, and the new place even more cannot let her sleep in her own room as her bedroom will be upstairs as my mother in law lives with me. So prob in a few years when she older
