You mentoined you tryed comparing him to a bag of food to carry around, ok i have 4 babies and only one arm and guess what , I can carry 2 at a time
is it difficult, yup but i love every mininut of it, i can give and do give just as much love to my furkids as the next, what im trying to tell you is , its not about the size, its about the love and joy they give you
I do hope you keep him, he is a doll,but if its not in your heart then you must rehome him.
