Low blood sugar 3am treatment for 2.5 child

I love to give GoGo Squeeze apple sauce to my 5 y/o daughter. http://www.gogosqueez.com/ One pouch has 15g of carbs, and you can stick it in his mouth and prod him to suck it right out. He doesn't even have to move or wake up. Plus, it's not pure liquid, which could make him urinate during the night. Also, the apple sauce usually brings up my daughter's BG nice and steady. And it comes in all different flavors. And it's healthy!

I tried the cheese and toast . At 3 he was ok. But by 7am he was 56 … any suggestion?
