Am I asking for too much?

Mommy can you sleep with me? Why you always go away when I just fallen asleep? I am insecure, I try to make myself awake and even if I sleep I will try to open my eyes once awhile to check whether you are around. I have some trick to ensure you can't walk away from me... I will lie on your body, sleep on your arm or hold on to your hand. Just to make you sleeping with me. I know you want me to be more independant but I am just 20mths old and the room is so dark, can you accompany me? Am I asking for too much? Please don't leave your dearest alone, okie?
