Having worked with BOTH animals and kids (and sometimes both at the same time, lol), I would choose kids, but NOT within a traditional education system. Here's why:
Most people who want to work with animals have a skewed idea of what it's like and the truth is that it's usually not at all what you expect. I worked for a veterinarian for seven years, at a zoo for two years, and then at museums with animal collections for 10 years, I can say that working with animals is dangerous, stressful, and physically tiring. It's usually underpaid work and loaded with emotional strife. Injured animals are not fun to deal with. If you work for a veterinarian, you frequently have to deal with idiot owners who don't care for their pets and you also assume the risk of being bitten and exposed to various chemicals. If you work at a zoo, you assume a major physical risk and believe me, cleaning up poo and chopping up food starts to lose it's appeal after awhile, even if you get to work with elephants. In my animal career, I have been bitten, stung, scratched, and mauled. I have hidden under a truck to avoid an angry cape buffalo, fought off an aardvark with a rake, and been bitten completely through the hand by -of all things- a golden retriever. And won't even get into the time when I had to gather up marijuana seeds out of pit bull poop to submit as evidence.
I have also worked with children for ten years as an educator in zoos and museums. It's really great becuase in this setting, the kids leave after a few hours and you get to see their fun, excited, best behavior side without having to deal with working within a school system. Sure, you get the rude one every now and then but overall you get to facilitate a really fun, educational experience for them. And did I mention that they go home after a couple of hours?
Also, working as an informal educator (someone who educates outside of the classroom) you usually spend only half your day with kids and the rest is spent doing research, designing new programs, etc. It's great work.
If you are interested in both animals and children, I would suggest that you look into a career as an environmental educator, where you can work in a zoo or museum and deliver programs to kids while utilizing live animals as education tools. Humane education is also on a similar vein. If you want more information about any of this, feel free to PM me.
