The babies are always more defensive than the older BPs. In my experience, they do get better. I have two that were always ready to strike but I handled them every time I cleaned the tubs, changed the water, etc. and they are way more relaxed now.
You might just have a feisty one, but she is probably just scared. She needs to learn that you are not going to eat her...lol. You can try gloves if it makes it easier for you. However, also from experience, their bites don't hurt much at all. I was bit by a 5 foot girl & it really wasn't that bad.
