Aw, I remember when my T+ girl was that itty! (newer pic below)
I do think that bloods are a more advanced snake, but I would recommend when you take the leap to start with a baby. My SSTP ("Black Blood") went through a testy stage when she was younger but I feel very proud of her from working with her though that to where she is now. I enjoy working with the snake as it grows.
As with anything, do a lot of research so you're as prepared as you can be!
