I wear Oscar high on my chest so the weight is mainly on my upper back. Any lower and the weight is taken by my lower back and I can't use it for as long. The pocket is usually firm but as he has got a little bigger it has been a little looser. I have one side supporting his head if it is turned to the side or my hand if he is facing me. I cover with both sides when he is asleep outside or if I am using it as a settling tool and want the dark.
