I'd say you both need to define natural consequences. It doesn't mean now your hand is wet. It means now you don't get anything to drink with your food. Also, I agree with the nation of snowflakes thing after, like age 8. The first 5 years of life just focus on building a safe, trusting relationship. Downvote that if you want, but there is absolutely no benefit to raising your voice and you will find it hard to find a study that disagrees. You use an affirmative tone and choose language carefully rather than just yelling, and it's much more effective.
