You and my mom sound very similar! I was diagnosed at age 15 with T1D, which shocked me, as well as my parents. My mom has always been a worry wart, but trust me she has gotten better with it! It is very normal for him to be experiencing lows, since he is a newly type 1 diabetic. Throughout the next couple of months, he will get a better idea how his body reacts to food and the insulin. Also, once you go back to the doctors for your checkups, the doctor might be able to change the insulin needs of your son! Trust me, it takes awhile to get that happy medium with your body. I am a nursing student so I get nerdy with some of the anatomy behind diabetes. Our body is like a balance beam, on one end is insulin and the other is food. If we eat too much carbs, we will be hyperglycemia. If we take too much insulin and not enough carbs, we will go into hypoglycemic. It takes a while to find that balance (homeostasis). Trust me, it does get better! I know my mom and I would sometimes get into small arguments at first, because truthfully we didn’t understand it all, still don’t. As sad as it is, I will have some high/low blood sugars with absolutely no reasoning behind it, just my body being weird. I hope this helps!
