I would give him a low carb snack now. . I’ll watch for the +2. I do have to go out shortly after that to collect kids from school.
Because it is so early in the cycle I would give him a higher carb snack and test again in 30 mins. I probably won’t be here in 30 mins but if he is still lowish I would repeat the snack as he has a few hours til nadir and test again 30 mins later again.I think it might be time for a MC snack now.
