Honestly no it doesn't bother me when children stare, it can bother me when adults stare. Let me explain.
I looooove kids reactions and then their parents reactions. It's one of my favorite things! Kids will all the sudden just stop, stare, do the look up/down, walk around me and then say to their parent HEY MOMMY that girl only has ONE leg!! I crack up because the parent usually goes in hush hush mode! Freaking out thinking that their kid has just offended me in some way, but I'm laughing. Normally if I see a child starting to stare or if I hear a child ask their parent I will turn to the child and talk to the child about it. This way I explain it to thid child and I am also showing the parent that I'm okay with it. Kids are awesome!! They will come up to me and ask me what happened to my leg. I have to sometimes be careful in answering that question because I dont want to freak them out and dont want them thinking it could happen to them. But once I have explained it they are like oh okay and then go about their way. Kids are so accepting and they are ready to move on after recieving an answer.
Adults are a different story. Dont get me wrong, I understand you don't see a one legged person walking around everyday (well enless you live in my house) so its different. We notice the differences in everything and everyone. Sometimes we see something that catches our eye and then our minds start to wonder and our thoughts take us 1,000 different places. We're not even really looking at the person because we are gazing into our thoughts but when that person looks at you they think you're staring, which you are but not really. But then there are times when people can't stop taking second and third looks. They want to know what happened or they are trying to figure out, do you only have one leg or is it just broken and I can't see their leg from this angle? Hey I get them all! I know that people stare at me ALL the time and I know it's not because of my super cute looks (haha) I know it's my leg and I'm fine with it. It just depends on how the look is given, but normally I'm okay with it. I would much rather someone asked me what happened for two reasons...1. I get to share the story that God has given me and tell them about how awesome He is! and 2. because once someone finds how why something happened then they stop staring.
But I just ask you to watch yourself when you stare at someone because you could cause them to have a complex. I'm completely secure with the way God has made me and I understand that people are just curious and interested. But not all people are like me where they are just getting used to their difference or they aren't as accepting of it, so just be careful
