I'm pretty sure you have been more than nice enough already. I would send one more email saying that there is no reason why you should not at least receive a picture update, a feeding update, and a weight update. That you are more than willing to wait for him to be ready, but you want to see how he is doing, and that there is no way that the breeder should not know which snake is yours, because how then are you supposed to know he sends the right one?
This makes me mad, and you are being too nice.
