Lacy - our daughter was 4 when she gave herself her first shot and it was by accident. She needed a shot and we were teaching a new babysitter when our daughter picked up the pen, put on the needle, primed it and gave herself a shot in the stomach. We followed along with her and she did everything correctly so we didn't stop her. After that, she wanted to do them all the time. We helped her set the doses until she never made any mistakes and then we let her do it on her own. She injected in her tummy for the longest time but now can do both arms and sometimes even her butt. She's now ten and has been doing it herself for at least the last three years. We are very fortunate in that she has expressed an interest in doing her own shots and testing and we never force her. She was ready to do it at a young age, but that doesn't mean other kids are ready, nor should they be forced to do it. We were supportive of her and she surprised us with how much control she wanted to have. We are working with her on calculating her own doses and she is coming along nicely, but we will not be ready to give her complete control for a while. Again, she WANTS to do this, and we are not forcing her. Different kids will be ready at different times, and we've found that being supportive has worked the best for us.
