With all respect to Anthracite, I think suggesting that DDG find a drug to take care of a child who doesn’t live at her house is expecting a little much.
DDG, my mom is a Type 1 diabetic and has been for 35 years. When she has an insulin reaction, she turns very pale, shakes slightly, gets all clammy, won’t answer questions, and acts extremely confused. She had a reaction while we were walking to her work a couple years ago, and I practically had to drag her there. She wanted to stop and look in all the stores, spoke very slowly, and would have gotten lost - on a path she’s walked a thousand times! - had I not been there to get her to work. Later I found out that she had sugar pills in her purse and felt like an idiot for not checking. Never assume that a diabetic will know that he or she is having an insulin reaction. If you ask my mom how she’s feeling while having one, she will persist in answering that she feels fine, nothing wrong at all. If you notice this little girl having any of these symptoms, get her some juice. Force her to drink it if necessary. If she’s not noticeably better after a couple glasses of OJ, it is time to call 911. It’s not as high tech as emergency shots, but it never fails with my mom - who hasn’t any significant problems with her diabetes since she was pregnant with me.
