Good Carbs Before 2nd Workout?

My son’s 2 a day schedule is 9-11am then 6-8pm

When should he eat before the 6pm practice and what?

mac n cheese?

You have to experiment on the time so as close to it as to not get sick. What well same thing and what is he practicing for??

Complex carbs are a good idea and can add a carb beverage during if desired
