hi @reneem, my opinion on this is just an opinion - a warning in advance I am not trying to offend.
pizza is easier to deal with when on a pump, but it is one of the hardest foods (second only to ice cream) to manage. pizza carbs can take 4-6 hours to absorb, because of the fat in the sauce and cheese. Ice cream has milk fat and sugar, the fat blocks absorption in me for at least 3 hours.
given that blood sugar control is imperfect anyway. I would say that it’s okay to be high once in a while. Once in a while it is just fine to get a 330 and have to drink water and walk and take a correction bolus or shot. NOw I realize that this is your baby, and that my blase attitude is heresy, and you wouldn’t dare risk it, but someday very soon he gets to completely control his diabetes, make his own mistakes, and deal with party food and drink. All you can do is prepare him for his eventual 100% ownership.
I treat myself to ice cream and I make the most awesome grilled pizza anywhere. I even drink beer with it. Yes it is hard to control. It took me many tries to get the insulin flow right with either fat/carb treat but I eventually did.
Now I must admit that I don’t do it every day, or even every week, but I do like my pizza and I give myself permission to eat it once in a while and deal with it. I also eat wedding cake, first birthday cake, candy at Halloween, and pretty much ice cream cake because… well… it talks to me.
in my opinion it is a mistake to forbid, or force limit food or be the food police. the problem is that the limits and the expectations are overwhelming. Once overwhelmed, for me, the pressure does more harm to my head than any high blood sugar would do to my body. The expectations to have perfect blood sugar all the time could influence pressure in a way that leads to or worsens depression or at least bad self image or self esteem.
this is a tough one. I don’t envy your position. good luck!
