its definately a clip for you tube
every day hes here , hes getting stronger..Im sure he is going to thrive with the one on one attention you are giving him.
I dont know much about raising tiny kittens..sorry... but if you arent already then keeping a weight chart could help, it msy not be apparent how much weight hes gaining when you are with him all the time, whilst when you can see him gaining weight it may set your mind at rest.
he does look adorable...i confess he has made me kitten broody
