hi David @Danielbgibbs, yes its possible you are wrong, it’s always possible to be wrong.
Many children under 12 have problems with bed wetting regardless of diabetes.
I found a study with the following data online: Bed-wetting was reported in 33% of 5-, 18% of 8-, 7% of 11-, and 0.7% of 17-years-olds.
I don’t know the circumstances of why your daughter moved in but if it was drastic or as a result of an issue (family, economic) the move itself can affect a young boy’s behavior.
9 is also a tough age to be dealing with a life-long chronic disease such as diabetes, and so there is probably behavior and other issues (depression) to look out for.
“sneaking” food is another issue entirely. in my opinion - your grandson needs flexibility in his life, his activities, and his diet and needs to become accustom to being able to eat anything he chooses, as long as testing and insulin are a part of it. There is really nothing he can’t eat as long as he also uses insulin to cover the sugar in the food (candy, ice cream pizza whatever). This may be a hard time for him, and so contact with a CDE (Certified diabetes educator) an endocrinologist, or a nutritionist whit type 1 experience may be of help.
high blood sugar can be related to more frequent urination, but I don’t knoo where his endo or pediatrician wants his overnight blood sugar to be. it’s pretty common for endo’s to want kids at 150 at night so they don’t risk overnight hypoglycemia, which can be more dangerous.
Hope you are doing ok and please let us know how your grandson is doing.
