Hopefully this will offer you a ray of hope. I have two now, one 26 months (my daughter) and a son who is 14 months. My daughter has two summers now under her belt (her first feild trip she was five months old) herping with daddy and my son has one. I am itching to get it started this weekend all over again.
I invested into an expensive shoulder/back pack that straps one of them in on my back and I carry the other one on my shoulders (there is some yelling sometimes from butt-in-the-face syndrome, but they change places enough to know it won't last forever). I highly recommend not going cheap on these. You can strap a kid in so they won't fall out and have a place for your water, milk bottles, bug jars and your camera.
They love going out in the field with me. We not only do all herps, but have had some good times chasing down butterflies while hanging on to daddy's chin hoping to not fall off. Yes they both have gotten faces full of branches, pricker bushes and muddy from going after turtles, but that never stops them from wanting to find out what is going to be under that next rock and if they can hold it. My kids have no fear of bugs and herps and there is nothing cooler than teaching a 2 year old to gently hold a butterfly, let it go and watch it fly into the sky.
Kids are tougher than you think. Give them the chance to prove it. Whether it is eating wasabi at 1 or getting stuck in rasberry bushes at two, I can promise you there are kids out there in tribes around the world that do the stuff as soon as they are born. Don't sell yours short. They will grow up loving getting their hands dirty and the looks on their faces when they hold a snake or watch a frog jump out of their hand back into the pond is just about the greatest thing there is on this planet. Have fun and don't be too safe...
