K..
This is just a general question - what is the deal with bedtime snacks? Aren't 3 meals and 2 snacks a day enough? I thought nighttime eating was bad, as it leads to over eating and obesity.
Honestly, when you said "snack", I thought you meant a banana, or peanut butter & crackers, not a happy meal WITH chocolate milk PLUS half & half, plus something else. That is a full meal, and not a very healthy one at that, right before bed. I'd be sick too.
My guess is that he's over eating & doesn't need the food at night.
