The joking "No!" from my 6 year old is messing with my head!

We have been doing a lot of work on having him be more listening and cooperative, because I got into the habit of allowing myself to be manuevered into having to ask him something over and over without compliance/response and then becoming very frustrated and yelling. I am working on lowering my frustration level, and don't want to be a yeller, and part of that is refusing to ask for things over and over. So the rule is, I ask, you get 1 reminder/follow up, but if I have to ask the third time there's a consequence. Typically a natural consequence. I make sure I have his attention and he hears me, when I ask (mild ADHD).Anyway, so his new "prank" on me is laughingly saying "No!" when I ask him to do something - but immediately getting up to do it.The first time, I asked him to go upstairs and do something and he said "No!" in a laughing voice. He turned back toward the TV instead of the stairs, but I somewhat suspected something based on his tone of voice. Thank goodness I've been working on slowing/calming my reactions, because I heard him pause the TV right away and then turn to go upstairs. Today, he did the same about brushing his teeth - a laughing "No!" while he was on the way into the bathroom. Not a bratty laugh, a 6 year old silly laugh.Anyway, he pointed out this morning that this 'prank' is funny because he's already doing the thing I asked. I am glad he didn't need to be told that. Hoping he doesn't get too big for his britches here, but right now it's a nice humorous component to an issue that was bringing he and I both a lot of stress. My mentality is he's working on what I asked him to work on, I'm working on what I value working on, and we're laughing together making it a positive experience. Might be embarrassing if we're in the grocery store or something but whatever. Hopefully I don't regret this in future.... via /r/Parenting https://ift.tt/2MGs6zP
