J.D.
From my limited experience (we have one girl and one boy), boys like the fun factor of learning how to use the potty, while girls like the clean factor of putting their pee and poop somewhere other than their panties. My daughter was elated to use the potty and virtually potty trained herself. She was able to pee and poop (with help wiping, of course) by about 2 and a couple of months. My son is 2 years, 8 months and has the peeing thing down, but is just starting with pooping in the potty.
I am a firm believer that when your child is ready, and I mean READY, it will happen. We have been trying about once a month with my son over the last 6 months to potty train. Only this last time has it clicked, and there's no looking back. We worry about so many things as parents, but I think this is one thing we just have to wait for. The child has to be ready. My son has been showing interest since he was around 18 months. Big sister was sitting on the potty, so it must be fun. But he was not ready. My mom and MIL kept pushing me, but when they're not ready, it's frustrating for everyone!
Good luck on this journey! Remember, motherhood is a marathon, not a sprint!
