I'm sure this has been discussed, but I can't seem to find any old threads on this topic. My son has pretty big post breakfast spikes. We prebolus about 20 minutes prior to eating. Breakfast tends to be his heaviest carb meal of the day (cereal or waffles). He eats around 7:30 am, then has snack at school around 9:30-10 at which time he is always 200-250, sometimes up to 285. By lunch time at school (1 pm) he is always between 90-140. On weekends, when he doesn't always have that snack he is within range 3-4 hours after breakfast so I tend to think increasing his breakfast bolus isn't the answer. Am I wrong? Are their other ways to decrease that spike or is this just one of those things I need to learn I can't control? Thanks for any suggestions.
