Babies do miss quite a bit. You have a normal, so highly unlikely that she has a wobble. Make sure you're heating the mouse properly, if not she could be confused(when I don't heat f/t properly, my snake strikes at me instead of the rat). Shaking the mouse around could also be messing her strike up. She'll get better as she gets older and sometimes they just miss.
However controversial the topic may be, I do agree with illaoi about the breeding of spiders. If the spider morph wasn't as pretty as it is, no doubt it would be bred way less and would be looked down upon more. I'm not a materialistic person, so I'll never own a snake with a genetic defect just because its pretty and attractive.
Now watch people come on this thread not even to help you or give you any advice OP, but just to try and defend spider morph![]()
