My toddler is in the throes of testing whether or not he has to obey. I feel like I have a handle on disciplining for things like hitting little sister, not eating his dinner, refusing to clean up his toys, but am SO struggling with what to do when he just outright won't obey something like "put your water on the table" and he looks at me with a smirk and throws it down and walks away or something. Just completely disregarding what I say in an effort to test my boundaries and will.

How do you handle those scenarios where their behavior doesn't really have an effect beyond just disobeying what they were instructed to do?
