I often soak it that way in the summer, I've been eating oatmeal with milk for more than 1 year now, and Quaker's oatmeal is the best, he and the milk don't care if it's hot or cold, just stir it a little bit and it'll be fine. Don't buy the early morning oatmeal, it's hard and has black impurities in it, and it's the same price as Quaker. I also knocked out half a tooth when I ate it, regret it.
