Baby rattlers more dangerous? Not really. Better chance of envenomation from a baby rattler bite? Sure. But concider a baby rattler is about 7 inches long and has fangs that could barely pierce thick human skin, much less jeans or boots, so I wouldnt worry to much about babies.
In my opinion, all the extra "snake protective" gear is over kill, but couldnt hurt. I will however, advise against any kind of snake bite kit. Youll never suck or draw any signifigant amount of venom out of tissue, surely not enough to make up for the valuable time wasted dickin with that kit you coulda been getting to a hospital.
75-100% of snake stories are bullshit, especially when it comes to size or agression. hearing a 6 foot rattler story from the badlands to me is the same as someone telling you guys about a 38 pound walleye they caught n released in the mouse river. A huge prairie rattler is 4ft, and average large adults are 3ft. In the extremely rare chance you do get bit, stay calm, and get to a hospital asap. But id be more worried about twisted ankles, or sunburns.
